Set indicator value of previous bar

[bonnies]

When ploting on a chart the value of the primary plot, I use the command:

Values[0].Set("somevalue");

to plot the value "somevalue" at the current bar. How can I modify the value of the indicator one bar ago? I tried something like the logic applied to other commands where first is the plot reference and then the bar number:

Values[0][1].Set("somevalue");

But the compiler says this command is wrong.
Sometimes I want to change the value plot of the indicator some bars ago. It is not always the same bar ago. Sometimes it is one bar ago and sometimes two bars ago. How can I change the plotted value?

Thank you

Hello bonnies,

Below is a link to the help guide on the DataSeries class.

DataSeries.Set(int barsAgo, double value)

Thank you for your answer Chelsea. I know that with the DataSeries class I can alter the value of it at any bar number. But, how can I plot it too? I mean I alter the value of the new dataseries 10 bars ago. How can I plot this new value of the indicator in the chart?

Thank you.

Hello bonnies,

A plot (Value) is a dataseries.

Set the plot and this will be how it appears on the chart.

I am sorry but I don't understand how to do it. I have read the "SampleSyncSecondarySeries" and "SampleBoolSeries" but any of these examples change the value plotted previously on the chart.
Could you provide some example, please?

Hello bonnies,

To set a plot 5 bars ago to the value of 100.

Value.Set(5, 100);
