I have developed a webpart library in which I have rendered a chart control. The code and steps are similar to the article from softwarefx.

The chart render for administrator account. But for not administrator it is displaying error.
403 unauthorized access.
I then created a custom security policy to give full trust.
<securityPolicy>
<trustLevel name="WSS_Medium" policyFile="C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\config\wss_mediumtrust.config" />
<trustLevel name="WSS_Minimal" policyFile="C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\config\wss_minimaltrust.config" />
<trustLevel name="CustomFullTrust" policyFile="C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\config\CustomFullTrust.config" />
</securityPolicy>
<trust level="CustomFullTrust" originUrl="" />
I assigned the Full trust for the webpart library and the chart fx dlls.
The CustomFullTrust.config is like follows
<CodeGroup
class="FirstMatchCodeGroup"
version="1"
PermissionSetName="Nothing">
<IMembershipCondition
class="AllMembershipCondition"

<CodeGroup

/>
</CodeGroup>
I also addded them as safe in the portal webconfig. But still I am facing the problem.
I noticed that creating the control in memory and assigning properties are not throwing the error it is coming from one statement in the code
this.Controls.Add(chtxData); where the control is loaded in the webparts CreateChildControls() process.
Just guessing (I think the error lies in temporary creating the image of the chart and the folder permissions are needed on some temporary folder where the chart image is first created)
Can some one help me on this
