Hello everybody.

What is the best way to pass 3 y-values to single x-value?

Currently i’m using XyyDataSeries + XyDataSeries

Don’t know, if it’s best approach?

  • Yura Khariton
    Hi Vlad. May I ask why do you need to have XyyyDataSeries? Do you use some custom renderable series to draw those values?
  • Vlad Semenov
    Hi, Yura. I have chart with 3 y values for 1 x value (x, y1, y2, y3). Basically it’s 3 lines

Hi Vlad,

Unfortunately we don’t support this case out of the box. So for now workaround with using band series to draw 2 lines without duplicating xValues looks like the best choice. Ideally to avoid duplication of values at all you would need to create custom renderable and data series. We have few examples of custom renderable series ( spline and animating line series ) but unfortunately we don’t have any examples of custom data series so if you want you can try to extend FastBandRenderableSeries and add third YValues collection as separate property for renderable series and then draw them directly in internalDraw() without creating custom data series. Alternatively you can contact our sales department and we can create desired functionality as part of short term consultancy project.

Best regards,
