We are using the Highchart bubble diagram, however when bubble x and y are on the same place in the diagram and bubble y is smaller there is no way to neither see nor much less click the smaller bubble.
Is there any way to plot the bigger bubbles first and then plot the smaller ones on top? Or a setting which says that smaller ones always are on top of the bigger ones?
Just sort the series data in descending order and pass it to the highcharts.
So that, the bigger bubbles will be plotted first and then the smaller ones, thereby the user will be able to hover on smaller as well as bigger bubbles.
Tried this in my project, and it's working perfectly fine !

I am plotting data where all 3 piece of data for a data point are in the same units.
While the bubble size is correct relative to the other bubbles, I would really like it to scale with the horizontal axis ie for the data below, I would like the bubble to to measure about 30 units across on the x axis.
x(mm)
y(mm)
colour
bubble (mm)
Bubble 1
5
5
1
30
Bubble 2
10
5
1
20
I am pretty sure this is not a native behaviour, and I only need a rough visual match, rather than a fully accurate representation.
Does anyone have any ideas how to bodge this?
Thanks!
I have tried multiplying up the values to enlarge bubble size, but it seems that the size of the largest bubble is fixed
As I only require a visual approximation have also looked at using AppScript to create this (my coding is basic at best) but, while I can open a drawing canvas, there does not seem to be any way to automatically create a drawing from there.
Suppose I want to create two charts with horizontal bars. The names of the objects are listed on the y-axis and the horizontal bars represents some quantity. The first chart has 100 items and the second chart has 5 items.
When I create the charts the horizontal bars have different widths. I'd like the bars to be the same width across all of my charts.
I know I can try different values for the height parameter to the AddShape function. But that seems time-consuming and unreliable since the number of items can change. I'd like to do something like:
Chart.BarWidth = 10
The "thickness" of each bar will be primarily determined by the number of data points that need to be plotted. The more data points to plot, the thinner the bars will be. There are some options to further tweak them, such as IChartGroup.GapWidth, and you're welcome to try to adjust this so that both charts match. But I suspect that it will be very difficult to do this reliably, particularly if the number of plotted points is expected to change over time.
To maintain the same bar thickness for multiple charts, I think your best option will be to ensure both charts' series refer to the same size range. So if your first chart refers to 100 cells, have your second chart refer to 100 cells, even if only 5 are populated with values. The empty cells should not plot but will still take up space and therefore maintain consistent bar thicknesses between your two charts.
I am using highchart to show bubble chart. Everything is working fine except in many cases there are lot of horizontal space(below min cirlce and above max cicle) and vertical space(left of lowest x and right of highest y). Because of this issue my chart sometimes seems very crowded even though there are some free space left in chart. I tried setting min/max of x/y axis but then it then clipped top/left circle. Is there any way i can instruct highchart to use all space in chart to draw bubbles.
I have created sample script at
`http://jsfiddle.net/ftghd9ny/1/`
In this demo you can see extra vertical space. X axis is showing fine. In some other cases there are extra space along x axis.
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'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.
