Percentage Scale

I want to compare several stocks on one chart with percentage scale and the problem I am having is that the percentage scale shows value from about 0 to 100 so if the percentage change for the stocks are within 5-10 % then the scale is not auto adjusting to zoom in on those and still shows 0 to 100% and it makes it very to hard to see the different line plot

The percentage scale should show values from 5 to 10% in your case. You probably have another time series that uses the percentage scale.
Please double check your formula or compare stocks again from an empty chart.

I am trying to compare sectors of S&P time series together on same percentage scale. The problem is the scale shows from 0 to 100 (instead of auto adjusting it from lowest value to highest value eg. 0 to 5%) so the line plot are all squished in the bottom and hard to differentiated. Please let me know if I am making my point clear if not I can try to send a picture of the plot to make it more clear.

I appreciate for the prompt response,

Thanks you

Please try comparing just two series in a new chart. It is currently showing 0 to 100, probably because another series (maybe volume or indicator) is also using the same percentage scale. That is why I asked you to just try with a very simple formula with two series only and work from there.

I tried two series with following code and percentage scale and its not working.

s0 = getseries('SPY', close);
s1 = getseries('XLB', close);

plot(s0, 'SPY', colorBlack, ChartLine, StyleOwnScale);
plot(s1, 'XLB', colorGold, ChartLine, StyleOwnScale);

You need to plot the currently selected symbol as well.

plot(close, ""); // For example

s1 = getseries('XLB', close);

plot(close, ""); // als tried plot(close, 'SPY', colorBlack, ChartLine, StyleOwnScale);
plot(s1, 'XLB', colorGold, ChartLine, StyleOwnScale);

percentage scale is autoadjusting for one series but as soon as I add another series it gets squished to the bottom and I have to manually expand the scale. Please plot this and you will know what I mean.

Thanks

Put "plot(close, "");" at the end to have all other series adjust to the main ticker.

The easiest way to do this would be to create a chart, click on the add indicator icon at the top/left corner of the chart, select "External Symbol", type a symbol, select "Close", check "Compare with current symbol" then click on "OK".
