How to show "Lines and Curves" in a log scale plot.
Analysis file contains a line chart that includes a “Lines & Curves” line based on “Line from column values”. On the line chart, the Y-axis is changed to to use a log scale. Once this change is made, the “Line from column values” disappears.
Changing the Line Chart to use a log scale on the Y-axis will cause the “Line from column values” to disappear.
The main line chart and the “Line from column values” are using different scales. Create a new calculated column that uses the same column as the Y-axis value using the function Log10() .
Then use the new calculated column in the “Line from column values” feature. This will add the line back under the log scale.
