How to make your first JavaScript chart with JSCharting

[pythonadventurer]

Hello. I completed this tutorial (How to make your first JavaScript chart with JSCharting) up to Step 2. When I refreshed my browser to view the bar chart, I got a “spinning ball”. I opened Chrome Developer Tools, and there is an error in jscharting.js : Uncaught TypeError: 1.indexOf is not a function. I Googled this issue and didn’t see anyone else who experienced this. Screenshot below. Am I doing something wrong here?

Thanks for your help.

We need to see your code, not the library code.

Without code, all we can do is help you interpret the error. It looks like somewhere you called indexofon a number instead of an array. Perhaps you called it on the index of an array by accident?

Thank you. I’ll look into that.
