Hide values in Graphics Chart

[Jakezer]

Hello,
I used this chart to show 2 Axes,
Now this specific chart uses that curve which adds a value as shown 11 and -1
Is there a way to avoid that turn that adds a value? Like a normal turn for example
Or simply I want to hide the number 11 and -1
I also want to change the bottom numbers (1, 2, 3, 4 and 5) to (A, B, C, D and E) but in this particular chart that option in the edit is locked, in other chart I managed to change them to letters ..
I want to use this chart because of its rounded turns when there's a change of value

Depending on the chart type you are using, you might be able to:

Hide the vertical-axis labels

Make the vertical-axis line invisible

Edit the Axis Labels (if a line chart, not for a scatter chart)

Hardcodes, or use a cell reference

On every chart you can actually insert any shape like a text box. And this could replace your "axis" labels (insert, position them then hide the axis labels as explained earlier).
