Vertical Gridlines are not drawn for Buble and Scatter charts

Hi,

Please run the sample below and see that vertical gridlines are not drwan for Scatter and Bubble charts.

Blue colored code is for bubble chart.
Yellow highlighted text to change code for scatter plot.
Red colored code is for Column chart, in which gridlines are working fine.

Thanks
Muhammed

Hi,

Thanks for your sample code.

We found the vertical gridlines issue regarding Bubble and Scatter chart. We will figure it out soon.

Your issue has been logged into issue tracking system with an issue id: CELLSJAVA-15197.

Thank you.

Hi,

After closely looking your code, we found your code is not fine.
For Bubble and Scatter charts, please replace the code:

chart.getCategoryAxis().getMajorGridLines().setVisible(true);
chart.getCategoryAxis().getMajorGridLines().setDashType(dashType);
to:
chart.getValueXAxis().getMajorGridLines().setVisible(true);
chart.getValueXAxis().getMajorGridLines().setDashType(dashType);


Thank you.

Working fine.
Thanks. Sorry for the mistake.

Hi,

Please try the attached version.

We have fixed the issue of generated image for Bubble chart.

Thank you.

The issues you have found earlier (filed as 15197) have been fixed in this update.
