Chart series - ShowNulls always true

[vineet]

Hi,

I have a very simple chart. It has a column where some values can be NULL and I want to hide these data points. But, as soon as I use my custom CacheHelper class, the setting to ShowNulls within chart series is ignored and they are all printed regardless.

StiWebViewer.CacheHelper = new StimulsoftViewerCacheHelper();

CacheViewer line commented (display is correct):

Correctly hiding the NULLs

CacheViewer line uncommented (display is wrong):

I have also attached a C# project if you want to replicate. You will have to restore packages from NuGet and build it again.

Cheers,
Vineet

I can replicate this behaviour by setting CacheMode = "StringCache" on the WebViewer tag:

<cc1:StiWebViewer ID="StiWebViewer1" runat="server" CssClass="vwr"
OnGetReportData="StiWebViewer1_OnGetReportData"
OnGetReport="StiWebViewer1_OnGetReport"
OnViewerEvent="StiWebViewer1_OnViewerEvent"
OnExportReport="StiWebViewer1_OnExportReport"
CacheTimeout="3600"
RequestTimeout="1200"
AllowAutoUpdateCache="True"
ShowServerErrorPage="False"
ParametersPanelPosition="Top" ParametersPanelColumnsCount="2"
ShowFullScreenButton="False"
ShowFindButton="False"
ShowPrintButton="False"
ShowSaveButton="False"
ToolbarDisplayMode="Simple"
ShowAboutButton="False"
UseCompression="False"
CacheMode="StringCache"></cc1:StiWebViewer>

Yes I do, the bug is happening as per my findings. If I don't use a custom cacheHelper and just set the CacheMode of the viewer to StringCache, "ShowNulls" is still being ignored.
