Is 'MarkerIndices' command available in any version of Matlab before 2016b by some other name or is there any similar function available in previous versions of Matlab?

Is 'MarkerIndices' command available in any version of Matlab before 2016b by some other name or is there any similar function available in previous versions of Matlab?

No, it is completely new as of R2016b. There was no previous functionality for it.

The work-around would be to plot twice:

MarkerIndices = [1 8 11 17 22]     %for example
plot(x, y, 'b-');                  %plot everything with appropriate line color and no marker
plot(x(MarkerIndices), y(MarkerIndices), 'b*');    %plot selectively with appropriate color and marker but no line

Thank you very much.

But this will mess up the legend. If I add a legend then there is going to be 2 different plots.

[Steven Lord]

Unless you explicitly tell legend which lines to include, yes the legend will include both lines.

x = 1:10;
y = x.^2;
lineToPlot = plot(x, y, 'k-');
hold on
lineNotToPlot = plot(x(1:3:end), y(1:3:end), 'ko');
legend(lineToPlot)

Compare this with:

x = 1:10;
y = x.^2;
lineToPlot = plot(x, y, 'k-');
hold on
lineNotToPlot = plot(x(1:3:end), y(1:3:end), 'ko');
legend show

Lets say that I have a command which goes like this:

x = 1:10;
y = x.^2;
lineToPlotA = plot(x, y, 'k-');
hold on
lineNotToPlotA = plot(x(1:3:end), y(1:3:end), 'ko');
legend('x and x^2')
hold on

lineToPlotB = plot(2*x, 2*y, 'k-');
hold on
lineNotToPlotB = plot(2*x(1:3:end), 2*y(1:3:end), 'ko');
legend('2x and 2x^2')

Here only the second legend is coming. What modification should i do to show the firsr legend also?
