How can I add an icon in a label?

I have 2 questions need your help.

  1. I would like to add a button on each plot to be a setting button. I use label with event listener and it works well ( as shown in attached file). However, my client asked me to change from normal text to graphic icon? How should I proceed?

  2. As you can see from the attached image, the third plot is macd series. The value rage is from -3e-8 to 3e-8 (by my observation). I manually set the maximum and minimum, and it get incorrect scale as shown.

    • How should I set the maximum and minimum for yScale?
    • I don't know how to get maximum and minimum value from a series. Can you suggest me?

Solution

  • A1 – Unfortunately, the current version of AnyChart doesn't provide an opportunity to add custom-made buttons inside the chart. But you can use a trick and use stage based layout. It means that the container includes a stage. The stage includes the stock chart all other elements by layers. Using this approach you can place an image (icon) upon the plot and set a listener just as for the 'settings' label. For details, please, check the sample in the comment below.

    A2 - We are planning to fix this behavior in 8.4.2 update (approximately by the end of November 2018). I will notify you when the fix becomes available. As a temporary workaround, you can get min /max value from your MACD indicator. For details, please, check the sample in the comment below. You can apply min/max to the yScale of plot #0 like this:

    chart.plot(0).yScale().minimum(minValue);
chart.plot(0).yScale().maximum(maxValue);
