Custom visual based upon existing visual

[jazfunk]

I am new to visualization development, (I'm not new to JS/TS/Node, etc), and am attempting to modify an open source Bullet Chart.  I've gone through the CircleCard tutorial and created my own visual.  Have studied the code for the MS Bullet Chart, and I'm slowly getting it all.

What I need to do is add additional "bands".   I've downloaded the project, modified the pbiviz.json file, changed the "guid", and some display names of some of the fields.  When I run this visual in developer mode via PowerBI service, I can see my changes.  When I package the visual and import it into PowerBI desktop, the field changes do not persist.  The new icon, and version information is showing properly, but not the field display names.

Any assistance is appreciated.

What is the process for extending an existing visual to create my own?

Hi @jazfunk ,

Oh, that's great! Thanks for letting me know such useful information.

And actually I have researched the issus for the past two days, and learn that it's necessary to replace the guid in every file for a new one, otherwise your fix will be replaced by the version on marketplace.

So could you please share the method and kindly Accept it as the solution so that other members could benefit from it?

The solution was to add a digit to the guid, then package the visual.  Thank you for the assistance.

Hi @jazfunk ,

As the official document said, You can change the display name of a visual in the pbiviz.json file. In the Visualizations pane, hovering over the icon reveals the display name.

Thank you for solution, however, I was able to change this information successfully, prior to posting this question.  

After working on this all weekend, I solved the problem.  I simply added some identifying digits to the end of the "guid", and all my changes appeared in the packaged visual.
