I'm trying to create a radar chart with the drawing style as polygon instead of circle in the MVC chart helper but i cannot find the AreaDrawingStyle anywhere in it.
I know in the regular ASP chart control i can do:
chart1.Series["Default"]["AreaDrawingStyle"] = "Polygon";
But in my MVC code, i have:
Chart myChart = new Chart(width: 600, height: 400)
.AddTitle("Chart Title")
.AddSeries(
name: "Employee",
chartType: "Radar",
xValue: new[] { "Peter", "Andrew", "Julie", "Mary", "Dave" },
yValues: new[] { "20", "60", "41", "55", "33" });
Does anyone know where to find it? I searched lots of places but i am having a hard time finding specific details about this particular type of chart.
I just had to make my MVC chart use polygon as well. This link helped me a lot by allowing me to style the chart using the underlying System.Web.UI.DataVisualization.Charting classes:
http://truncatedcodr.wordpress.com/2012/09/18/system-web-helpers-chart-custom-themes/
In short, try this nasty stuff...
System.Web.UI.DataVisualization.Charting.ChartArea ca = new System.Web.UI.DataVisualization.Charting.ChartArea("Default");
var chart = new System.Web.UI.DataVisualization.Charting.Chart();
chart.Series.Add("MySeries");
chart.Series["MySeries"]["AreaDrawingStyle"] = "Polygon";
var cs = chart.Serializer;
cs.IsTemplateMode = true;
cs.Format = System.Web.UI.DataVisualization.Charting.SerializationFormat.Xml;
var sb = new System.Text.StringBuilder();
using ( System.Xml.XmlWriter xw = System.Xml.XmlWriter.Create(sb))
{
cs.Save(xw);
}
string theme = sb.ToString().Replace("<?xml version=\"1.0\" encoding=\"utf-16\"?>", "");
System.Web.Helpers.Chart myChart = new System.Web.Helpers.Chart(width: 1024, height: 768, theme:theme);
And now you have a whole new name space to look into for formatting your charts!

I'm trying to access the properties of the following widget:
local cpu_widget = wibox.widget{
{
max_value = 100,
paddings = 1,
border_width = 2,
widget = wibox.widget.progressbar,
},
{
font = beautiful.font_type .. "8",
widget = wibox.widget.textbox,
},
forced_height = 100,
forced_width = 20,
direction = 'east',
layout = wibox.container.rotate,
}
I've tried through the conventional way, using cpu_widget[1].value or cpu_widget[2].text, but that didn't work.
Any thoughts on how I could do that?
See the "Accessing Widgets" on https://awesomewm.org/doc/api/documentation/03-declarative-layout.md.html (I can't seem to link to this section directly)
Basically: You can add id = "bar" and id = "text" to your widgets and use these identifiers to retrieve the widgets again.
In case Elv13 ever sees this answer: You did great work on the docs!
I'm trying to create a custom world map where countries are merged into regions instead of having individual countries. Unfortunately for some reason something seems to get messed up with the winding order along the process.
As base data I'm using the natural earth 10m_admin_0_countries shape files available here. As criteria for merging countries I have a lookup map that looks like this:
const countryGroups = {
"EUR": ["ALA", "AUT", "BEL"...],
"AFR": ["AGO", "BDI", "BEN"...],
...
}
To merge the shapes I'm using topojson-client. Since I want to have a higher level of control than the CLI commands offer, I wrote a script. It goes through the lookup map and picks out all the topojson features that belong to a group and merges them into one shape and places the resulting merged features into a geojson frame:
const topojsonClient = require("topojson-client");
const topojsonServer = require("topojson-server");
const worldTopo = topojsonServer.topology({
countries: JSON.parse(fs.readFileSync("./world.geojson", "utf-8")),
});
const geoJson = {
type: "FeatureCollection",
features: Object.entries(countryGroups).map(([region, ids]) => {
const relevantCountries = worldTopo.objects.countries.geometries.filter(
(country, i) =>
ids.indexOf(country.properties.ISO_A3) >= 0
);
return {
type: "Feature",
properties: { region, countries: ids },
geometry: topojsonClient.merge(worldTopo, relevantCountries),
};
}),
};
So far everything works well (allegedly). When I try to visualise the map using github gist (or any other visualisation tool like vega lite) the shapes seem to be all messed up. I'm suspecting that I'm doing something wrong during the merging of the features but I can't figure out what it is.
When I try to do the same using the CLI it seems to work fine. But since I need more control over the merging, using just the CLI is not really an option.
The last feature, called "World", should contain all remaining countries, but instead, it contains all countries, period. You can see this in the following showcase.
var w = 900,
h = 300;
var projection = d3.geoMercator().translate([w / 2, h / 2]).scale(100);
var path = d3.geoPath().projection(projection);
var color = d3.scaleOrdinal(d3.schemeCategory10);
var svg = d3.select('svg')
.attr('width', w)
.attr('height', h);
var url = "https://gist.githubusercontent.com/Flave/832ebba5726aeca3518b1356d9d726cb/raw/5957dca433cbf50fe4dea0c3fa94bb4f91c754b7/world-regions-wrong.topojson";
d3.json(url)
.then(data => {
var geojson = topojson.feature(data, data.objects.regions);
geojson.features.forEach(f => {
console.log(f.properties.region, f.properties.countries);
});
svg.selectAll('path')
// Reverse because it's the last feature that is the problem
.data(geojson.features.reverse())
.enter()
.append('path')
.attr('d', path)
.attr('fill', d => color(d.properties.region))
.attr('stroke', d => color(d.properties.region))
.on('mouseenter', function() {
d3.select(this).style('fill-opacity', 1);
})
.on('mouseleave', function() {
d3.select(this).style('fill-opacity', null);
});
});
path {
fill-opacity: 0.3;
stroke-width: 2px;
stroke-opacity: 0.4;
}

To fix this, I'd make sure to always remove all assigned countries from the list. From your data, I can't see where "World" is defined, and if it contains all countries on earth, or if it's a wildcard assignment.
In any case, you should be able to fix it by removing all matches from worldTopo:
const topojsonClient = require("topojson-client");
const topojsonServer = require("topojson-server");
const worldTopo = topojsonServer.topology({
countries: JSON.parse(fs.readFileSync("./world.geojson", "utf-8")),
});
const geoJson = {
type: "FeatureCollection",
features: Object.entries(countryGroups).map(([region, ids]) => {
const relevantCountries = worldTopo.objects.countries.geometries.filter(
(country, i) =>
ids.indexOf(country.properties.ISO_A3) >= 0
);
relevantCountries.forEach(c => {
const index = worldTopo.indexOf(c);
if (index === -1) throw Error(`Expected to find country ${c.properties.ISO_A3} in worldTopo`);
worldTopo.splice(index, 1);
});
return {
type: "Feature",
properties: { region, countries: ids },
geometry: topojsonClient.merge(worldTopo, relevantCountries),
};
}),
};
I am using google charts to display a stacked column chart. I am using entity framework and linq queries to gather my data from the db.
The problems I am having is:
that it will not order the chart. I have ordered the chart but the x-axis remains un-ordered. Can this be done through the linq query or could I do it in the script?
Currently it only displays x-axis values for data that I have. Example is on the x-axis I have month number but it only displays marks for data I have eg. 1,4,5,6. Is there a way to include from 1-12 although there is no data for that particular month number?
Code:
#region Total Hours Per Month sick
var querythpshols = (from r in db.HolidayRequestForms
where (r.StartDate) >= dateAndTime
group r by r.MonthOfHoliday into g
select new { Value = g.Key, Count = g.Sum(h => h.HoursTaken)});
var resultthpshols = querythpshols.ToList();
var datachartthpshols = new object[resultthpshols.Count];
int G = 0;
foreach (var i in resultthpshols)
{
datachartthpshols[G] = new object[] { i.Value.ToString(), i.Count };
G++;
}
string datathpshols = JsonConvert.SerializeObject(datachartthpshols, Formatting.None);
ViewBag.datajthpshols = new HtmlString(datathpshols);
#endregion
#region Total Hours Per Month
var querythpshols1 = (from r in db.HolidayRequestForms
where (r.StartDate) <= dateAndTime
group r by r.MonthOfHoliday into g
select new { Value = g.Key, Count1 = g.Sum(r => r.HoursTaken) })
;
var resultthpshols1 = querythpshols1.ToList();
var datachartthpshols1 = new object[resultthpshols1.Count];
int P = 0;
foreach (var i in resultthpshols1)
{
datachartthpshols1[P] = new object[] { i.Value.ToString(), i.Count1 };
P++;
}
string datathpshols1 = JsonConvert.SerializeObject(datachartthpshols1, Formatting.None);
ViewBag.datajthpshols1 = new HtmlString(datathpshols1);
#endregion
Script:
#*TOTAL HOURS PER MONTH CHART*#

var datassthpshols = JSON.parse(datathpshols);

};
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.ColumnChart(document.getElementById('chartTHPShols_div'));
chart.draw(joinedData, options);
}
</script>
1) Use data table method --> sort -- to order the x-axis.
joinedData.sort([{column: 0}]);
2) strings produce a discrete axis, and will only display the data available. numbers produce a continuous axis, and provide much more flexibility for the axis ticks. probably the most simplest solution would be to use a data view to convert the x-axis to numbers. (use the data view to draw the chart)
var joinedData = google.visualization.data.join(data1, data2, 'full', [[0, 0]], [1], [1]);
var dataView = new google.visualization.DataView(joinedData);
dataView.setColumns([{
calc: function (dt, row) {
return parseFloat(dt.getValue(row, 0));
},
label: joinedData.getColumnLabel(0),
type: 'number'
}, 1, 2]);
chart.draw(dataView, options);
I'm making a sunburst with Highcharts .NET,
This is how i setup the chart:
Highcharts higcharts = new Highcharts
{
Chart = new Chart
{
Type = ChartType.Sunburst,
Width = 700,
Height = 700
},
Title = new Title
{
Text = "Monthly Average Temperature",
X = -20
},
Subtitle = new Subtitle
{
Text = "Source: WorldClimate.com",
X = -20
},
Legend = new Legend
{
Layout = LegendLayout.Vertical,
Align = LegendAlign.Right,
VerticalAlign = LegendVerticalAlign.Middle,
BorderWidth = 0
},
Series = new List<Series>
{
new SunburstSeries
{
Name ="Test",
Data = data,
//LevelSize = new SunburstSeriesLevelSize
//{
// Unit = SunburstSeriesLevelSizeUnit.Percentage,
// Value = 100
//},
Levels = new List<SunburstSeriesLevels>
{
new SunburstSeriesLevels
{
LevelSize = new SunburstSeriesLevelsLevelSize{
Unit = SunburstSeriesLevelsLevelSizeUnit.Percentage,
Value = 90
}
},
new SunburstSeriesLevels
{
LevelSize = new SunburstSeriesLevelsLevelSize{
Unit = SunburstSeriesLevelsLevelSizeUnit.Percentage,
Value = 10
}
}
}
}
}
};
I tried many ways but the levels radius never change, did i miss something?
The only one working is the levelsize of the entire serie but i need to set the size for a specific level.
I tried to search but it looks like nobody already encountered any problem.
Level's object levelSize is able do control the size of individual level. It has two properties: unit (pixels / percentage / weight) and value (determined by the unit):
levels: [{
level: 1,
levelIsConstant: false,
levelSize: {
unit: 'pixels',
value: 30
}
}, {
level: 2,
colorByPoint: true,
dataLabels: {
rotationMode: 'parallel'
}
}, {
level: 3,
levelIsConstant: true,
levelSize: {
unit: 'weight',
value: 2
}
}, {
level: 4,
levelIsConstant: true,
levelSize: {
unit: 'percentage',
value: 30
}
}]

What would be the easiest way possible to display custom properties in the pie chart tooltip?
var pieData = [
{
value: 40,
color:"#F7464A",
highlight: "#FF5A5E",
label: "Label 1",
description: "This is a description for label 1"
},
{
value: 60,
color: "#46BFBD",
highlight: "#5AD3D1",
label: "Label 2",
description: "This is a description for label 2"
}
];
var options = {
tooltipTemplate: "<%= label %> - <%= description %>"
};
window.onload = function(){
var ctx = document.getElementById("chart-area").getContext("2d");
window.myPie = new Chart(ctx).Doughnut(pieData, options);
};
I tried simply adding a "decription" property and then printing it, but without any luck. It just gives me an error saying description is not defined. I saw that there is a custom tooltip functionality, but that seemed like a lot of work for something trivial. Is there an easier way?
Charts doesn't support this feature officially. But you can customize tooltip with your data like this in case of LineChart.
first, make chart with datasets and options
var chart = new Chart(ctx).Line(dataset, opt);
and, add properties what you want show in tooltip
var points = chart.datasets[0].points;
for (var i = 0; i < points.length; i++) {
// Add properties in here like this
// points[i].time = '2015-04-23 13:06:24';
}
then, you can use these properties like this.
tooltipTemplate: "<%=time%> : <%=value%>"
I hope this is helpful to someone. :D
You should go:
var options = {
tooltipTemplate: "<%= label + '-' + %> <%= description %>"
};
It's not a solution really, but I solved it by adding just the description inside the label...
label: "Label 2 - Description",
