Vaadin Charts 3.0.0 - Grid Lines in multiple axis chart

Flow
1

Hi,

I build a “multichart”, a chart with multiple Y-Axis (three linear to be precise) and one DateTime X-Axis.
On two of the Y-Axis, Columns charts are displayed, on the last one a series chart.

I’m trying to display the grid lines on the background of the charts but setting the gridLine width and color on all the axis did’t worked.

Any suggestion?

Thanks in advice.

Hi,

Have you seen this demo?
http://demo.vaadin.com/charts/#MultipleAxes

Are those horizontal grid lines the ones you want to show? Or did I miss something?

Thanks for your answer and sorry for the delay.

Yes they are the grid lines we want to show, but what we would like to do (as we did with our old UI framework) is to have multiple charts stacked on on top of the other in the same (multi)chart, not overlapped as they are in the demo.

We are able to draw them stacked charts using different Y axis, but we are not able to draw the background grid lines.

Ok, I get the point now.

Could you provide a small example of stacked charts with multiple axis where you can’t see the grid lines?

Regards

Attached you can find a screenshot of my test with a Area charts on top and a series chart on bottom.

Here is an excerpt of the Y axis configuration:

            yAxis.setType(AxisType.LINEAR);
            
            yAxis.setGridLineWidth(2);
            yAxis.setGridLineColor(SolidColor.BLACK);
            yAxis.setTickInterval(20);
            
            yAxis.setLineWidth(2);

Test out if the order that you add the data series have an affect on anything. First data series usually has priority when configuring global matters. Try with one data series, and when the gridlines are visible, try to add the second. See in which moment it breaks. Is it some certain series type that breaks it?
