Some questions regarding funnel charts and charts in general.



Hi. I just started checking out jchartfx to see if it suits our needs and while it looks promising there are a couple of questions that I need sorting out.


  • Is there a way to remove the background and border of the chart?
  • Can I remove the legend and incorporate it into the label somehow? Funnel charts are quite big and the legend takes up a lot of space. I was thinking of making the labels look like "Item name, value".
  • Is there a fast way to add tooltips and links to the labels/sections of the funnel (and bars/slices for bar/pie charts) or do I have to implement them myself?
  • And lastly; Is there a way to make sure the value labels don't overlap? The labels overlap badly in the case of funnel charts with small sections.
  • I almost forgot: What kind of formatting do you use with the chart1.getAllSeries().getPointLabels().setFormat(); methods? I want to format it as float with two decimal digits if possible, or just float and i'll calculate within two decimals myself if needed. Your example uses %v but that doesn't show decimals at all.
Thanks in advance.

You can remove the border as follows


To remove the border you have a couple of options, if you are using our CSS you can edit it and make sure the fill for .jchartfx .Border is set to the same color as your page or transparent. If you are not using our CSS you can use. In general if you include our CSS that would be the way to change colors, line widths, etc. If you do not include our CSS then you can use our API to change those visual properties.

To show and change the text for the labels


    chart1.getAllSeries().getPointLabels().setFormat("%l, %v");

Tooltips are handled automatically by the library, you can change the text that appears for the tooltips using our API or handling an event. We do not have special support for labels but you can handle an event when the user clicks on a bar/marker

Unfortunately there is no property to make sure labels do not overlap.

Thanks for the help. That covers all the problems except for the Numbers overlaping, which is the most obvious one for the user. I absolutely need to find a solution to it. Is there a way to make the labels appear on alternating sides of the funnel? for example one label to the left of it, the other to the right, and so on?
