Graduated Colors Rendering Doesn't Work With Negative Values

DominicChen

I'm trying to rendering a point feature layer with graduated colors rendering and manual interval method using Pro SDK. The field is double format. The values of all records of that field are negative. I take a reference from ProSnippets Render and ArcGIS Pro SDK Community Sample Code and implement the code. However, the rendering regards all the negative values as out-of-range and fails to render with correct symbol. If I apply with another break method (e.g. natural break) or with positive values, it won't have that problem.

Here are the code snippets:

Could anyone give some advice or ways to work around? Thank you very much.
