I successfully drawn a multiline chart using Charts library in Swift. However there is a minor customisation I need. Looking up the documentation I haven't found anything relative in the properties of datasets and line chart.
Here's slice of screenshot from my multiline chart.
My requirement is all the lines should start from Y-Axis but the first nodal point which is on Left axis shouldn't have a circle on it e.g the (0, 30) point.
Remaining all the nodal points must have a circle on them as shown in the image. Is any property out there in any class which toggles off the first nodal point or any other alternate customization I can do to achieve this?

I am displaying pie chart and drawing labels outside of chart itself. Sometimes I must display odd data, that one point takes up 90% of chart so the rest must "mash up" into remaining 10% of the chart. Everything is okay, but the labels (slice names) are also "mashing up". So I implemented mechanism that "sorts out" those labels not to collide with each other. Now I have a "word cloud" above my chart, since the biggest slice is always facing down, leaving all other slices facing up. That is my problem: I want to rotate the chart so that the biggest value data point would be facing left (leaving me right side of chart for labels).
So my question is:
How I could rotate pie chart around its center by code?
And rotating whole chart view is not an option since labels must remain horizontal.
So i found the solution myself:
you can use this code:
[(SChartDonutSeries*)[[chart series] firstObject] setRotation:-1.570];
To rotate first (the only in my case) DonutSerie by approx -90 degrees with this line of code. I use it in this delegate method:
sChartRenderFinished
I have two series in my highchart. One bar and one line chart. I want the datapoints of the line chart be represented at rectangle or straight lines instead of dots. Is that possible?
Are you looking for "square"? Explained here.
I am using core plot framework for drawing the line graph in iPhone and it is working fine.I am displaying system time on X- axis and Temperature on Y- axis.I need to draw the cross hair vertical line that indicate the selected value on the line graph. for example
I would highly appreciate if someone can give me some suggestion to solve this issue.
Thanks in advance.
You can use another axis or scatter plot to draw the line. Using an axis is simpler if all you need is a single horizontal or vertical line. Set all of the tick and grid line styles to nil and use the orthogonalCoordinateDecimal to position it in the correct location. There is a demo using a scatter plot to draw a crosshairs over the selected point in the Mac version of the CPTTestApp example app.
I am designing an HighCharts bubble chart (a matrix with coloured fields, drawn using SVG), that should have some text explaining the axis values outside of the actual chart area.
That is, because the axis values are A-E and need a lengthy explanation (A = Always exceeds goals bla bla etc.).
These explanations should be visible - next to the chart, not in it, and not in tooltips because these cannot be printed.
My question: Can I put SVG <text/> outside of the plot area? HighCharts seems to stretch the plot area as far as it can, leaving no space to either side.
You can use text text and define css styles i.e: position:absolute;left:20px;top:20px;
I'm trying to customize a Coreplot graph in many ways I can and the next thing I would like to do is place the X Axis Labels (one that is custom as well) at the bottom of the graph, independent of the X axis' position (whether it's scrolled up or down).
To make it clear, it is similar to giving the labels an offset value of something like 50.0. But offset is not the property I'm looking for since it fixes the labels location relative to the X axis.
Any way this can be done? Or do I have to skip the axisLabels property and place and layer or something manually at the bottom of the graph?
EDIT: Alright, I managed to place an axis on the bottom with CPTConstraints. But it's not on the bottommost. If a plot point is on those levels, the plot line overlaps the labels. I tired padding of the graph but of course, it moves the whole graph, hence the issue persists.
Thanks in advance
Make a second x-axis. Have the first one draw the axis line, tick marks, etc., as normal but no labels. Label the second one and set all of the line style properties to nil so it doesn't draw any of the lines.
Turns out that aside from the graph, the plotAreaFrame property of the CPTGrpah also has paddings. If you give more paddings to plotAreaFrame than that of the graph, the plot will be drawn in a smaller frame and the rest of the graph area will be for you to add what you want (i.e., a second Axis).
Big thanks to #Eric, for trying to answer Every single CorePlot question as soon as possible.
CorePlot does have a lot of customisation than I thought.
