Also, at this time, if you change "100000000" on line 29 to "1000000", it will work properly.</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="タイトルなし3.png" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/102788iE6E14006608AC5F8/image-size/medium?v=v2&amp;px=400" role="button" title="タイトルなし3.png" alt="タイトルなし3.png" /></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="タイトルなし4.png" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/102789iA40823DED6D3EADF/image-size/medium?v=v2&amp;px=400" role="button" title="タイトルなし4.png" alt="タイトルなし4.png" /></span></P><P>Why does this happen?</P><P>The image below shows a slightly more complex code.<BR />The color of the "3" square has changed.</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="タイトルなし.png" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/102791iEC5DD59ACBC3A123/image-size/medium?v=v2&amp;px=400" role="button" title="タイトルなし.png" alt="タイトルなし.png" /></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="タイトルなし2.png" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/102792i99C82BF22DDCF318/image-size/medium?v=v2&amp;px=400" role="button" title="タイトルなし2.png" alt="タイトルなし2.png" /></span></P><P>I don't know the cause of this either.</P><P>Is there any way to solve it? thank you.</P> Thu, 02 May 2024 07:53:18 GMT https://community.esri.com/t5/python-questions/the-behavior-of-classbreaks-upperbound-changes/m-p/1417959#M70510 -_- 2024-05-02T07:53:18Z https://community.esri.com/t5/python-questions/the-behavior-of-classbreaks-upperbound-changes/m-p/1417970#M70511 <P>perhaps you understand this comment</P><P><EM>If you change upperBound of a ClassBreak, the classificationMethod automatically changes to ManualInterval.
