I had made that mistake first, and without the handlers I was getting the Red X instead of an image.  Once I fixed that, it became just the blank image.

Hi Zac,

Most likely you're missing the http handlers registration in the sharepoint web.config file - you'll need the following two handlers:

<add name="NevronChart" preCondition="integratedMode" verb="*" path="NevronChart.axd" type="Nevron.Chart.WebForm.NChartImageResourceHandler"/>
<add name="NevronScriptManager" preCondition="integratedMode" verb="*" path="NevronScriptManager.axd" type="Nevron.UI.WebForm.Controls.NevronScriptManager"/>

You can also consider to use the Nevron Chart for Sharepoint solution which integrates natively in SharePoint and also allows for compete programability via the code injection feature.

I'm trying to deploy a .NET chart on an aspx page within SharePoint.  Using just the example provided here under Web Control -> Getting Started -> Basic Chart, http://examplesaspnetchart.nevron.com/ , I'm getting just a blank white space where the image should be.

I can use the following, along with setting up a directory, to get the chart to display as a workaround, but it'd be nice to know if I could get it working without doing so: 

nChartControl1.ImageAcquisitionMode = Nevron.UI.WebForm.Controls.ClientSideImageAcquisitionMode.TempFile;
