Hello,

I would like to plot 2 sets of data on the same x-axis, but the x-axis is discontinued. In the first range, R1, the x-axis should cover 0-10. In the second range, R2, the x-axis should cover 40-50. In both ranges I would like to plot y1 on the left axis, and y2 on the right axis. I used the example for Plotting Data on a Discontinuous x-Axis as a template. I can plot a discontinued x-axis with y1 in both ranges linked to the left y-axis. Please see my code below:

x_R1 = 0:10;

y1_R1 = rand(1,11)*10;

y2_R1 = rand(1,11)*100;

x_R2 = 40:50;

y1_R2 = rand(1,11)*10;

y2_R2 = rand(1,11)*100;

figure

t = tiledlayout(1,2,'TileSpacing','tight');

bgAx = axes(t,'XTick',[],'YTick',[],'Box','off');

bgAx.Layout.TileSpan = [1 2];

ax1 = axes(t);

plot(ax1,x_R1,y1_R1, 'b')

xline(ax1,10,':');

ax1.Box = 'off';

xlim(ax1,[0 10])

ax2 = axes(t);

ax2.Layout.Tile = 2;

plot(ax2,x_R2,y1_R2, 'b')

xline(ax2,40,':');

ax2.YAxis(1).Visible = 'off';

ax2.Box = 'off';

xlim(ax2,[40 50])

linkaxes([ax1 ax2], 'y')

But, when I add the second set of data, y2, using yyaxis right, the y1 data loses the link to the left y-axis. Please see below:

x_R1 = 0:10;

y1_R1 = rand(1,11)*10;

y2_R1 = rand(1,11)*100;

x_R2 = 40:50;

y1_R2 = rand(1,11)*10;

y2_R2 = rand(1,11)*100;

figure

t = tiledlayout(1,2,'TileSpacing','tight');

bgAx = axes(t,'XTick',[],'YTick',[],'Box','off');

bgAx.Layout.TileSpan = [1 2];

ax1 = axes(t);

ax1.Layout.Tile = 1;

plot(ax1,x_R1,y1_R1, 'b')

%Add right y-axis data to R1

yyaxis right

plot(ax1, x_R1,y2_R1, 'r');

%

ax1.YAxis(2).Visible = 'off';

xline(ax1,10,':');

ax1.Box = 'off';

xlim(ax1,[0 10])

ax2 = axes(t);

ax2.Layout.Tile = 2;

plot(ax2,x_R2,y1_R2, 'b')

%Add right y-axis data to R2

yyaxis right

plot(ax2, x_R2,y2_R2, 'r');

%

xline(ax2,40,':');

ax2.YAxis(1).Visible = 'off';

ax2.Box = 'off';

xlim(ax2,[40 50])

linkaxes([ax1 ax2], 'y')

Is there anyway to create this discontinued x-axis plot, where the y1 data is linked to the left y-axis, and the y2 data is linked to right y-axis?

Thank you!

I changed your values to make it easier to see what's going on, but it looks fine to me (see below). I also tested in 2022b with the same results. Can you post a screen shot of the results you're getting?

x_R1 = 0:10;

y1_R1 = 0:1:10;

y2_R1 = 100:-10:0;

x_R2 = 40:50;

y1_R2 = 10:-1:0;

y2_R2 = 0:10:100;

figure

t = tiledlayout(1,2,'TileSpacing','tight');

bgAx = axes(t,'XTick',[],'YTick',[],'Box','off');

bgAx.Layout.TileSpan = [1 2];

ax1 = axes(t);

plot(ax1,x_R1,y1_R1, 'b')

xline(ax1,10,':');

ax1.Box = 'off';

xlim(ax1,[0 10])

ax2 = axes(t);

ax2.Layout.Tile = 2;

plot(ax2,x_R2,y1_R2, 'b')

xline(ax2,40,':');

ax2.YAxis(1).Visible = 'off';

ax2.Box = 'off';

xlim(ax2,[40 50])

linkaxes([ax1 ax2], 'y')

x_R1 = 0:10;

y1_R1 = 0:1:10;

y2_R1 = 100:-10:0;

x_R2 = 40:50;

y1_R2 = 10:-1:0;

y2_R2 = 0:10:100;

figure

t = tiledlayout(1,2,'TileSpacing','tight');

bgAx = axes(t,'XTick',[],'YTick',[],'Box','off');

bgAx.Layout.TileSpan = [1 2];

ax1 = axes(t);

ax1.Layout.Tile = 1;

plot(ax1,x_R1,y1_R1, 'b')

%Add right y-axis data to R1

yyaxis right

plot(ax1, x_R1,y2_R1, 'r');

%

ax1.YAxis(2).Visible = 'off';

xline(ax1,10,':');

ax1.Box = 'off';

xlim(ax1,[0 10])

ax2 = axes(t);

ax2.Layout.Tile = 2;

plot(ax2,x_R2,y1_R2, 'b')

%Add right y-axis data to R2

yyaxis right

plot(ax2, x_R2,y2_R2, 'r');

%

xline(ax2,40,':');

ax2.YAxis(1).Visible = 'off';

ax2.Box = 'off';

xlim(ax2,[40 50])

linkaxes([ax1 ax2], 'y')

Hi,

I see your point. I changed the values again to make the problem more clear. Here's the output with data for just one y-axis:

x_R1 = 0:10;

y1_R1 = 0:10;

y2_R1 = 100:-1:90;

x_R2 = 40:50;

y1_R2 = 10:20;

y2_R2 = 90:-1:80;

figure

t = tiledlayout(1,2,'TileSpacing','tight');

bgAx = axes(t,'XTick',[],'YTick',[],'Box','off');

bgAx.Layout.TileSpan = [1 2];

ax1 = axes(t);

plot(ax1,x_R1,y1_R1, 'b')

xline(ax1,10,':');

ax1.Box = 'off';

xlim(ax1,[0 10])

ax2 = axes(t);

ax2.Layout.Tile = 2;

plot(ax2,x_R2,y1_R2, 'b')

xline(ax2,40,':');

ax2.YAxis(1).Visible = 'off';

ax2.Box = 'off';

xlim(ax2,[40 50])

linkaxes([ax1 ax2], 'y')

And here is the output when I try to display the second set of data on the right y-axis:

x_R1 = 0:10;

y1_R1 = 0:10;

y2_R1 = 100:-1:90;

x_R2 = 40:50;

y1_R2 = 10:20;

y2_R2 = 90:-1:80;

figure

t = tiledlayout(1,2,'TileSpacing','tight');

bgAx = axes(t,'XTick',[],'YTick',[],'Box','off');

bgAx.Layout.TileSpan = [1 2];

ax1 = axes(t);

plot(ax1,x_R1,y1_R1, 'b')

yyaxis right

plot(ax1, x_R1,y2_R1, 'r');

ax1.YAxis(2).Visible = 'off';

xline(ax1,10,':');

ax1.Box = 'off';

xlim(ax1,[0 10])

ax2 = axes(t);

ax2.Layout.Tile = 2;

plot(ax2,x_R2,y1_R2, 'b')

yyaxis right

plot(ax2, x_R2,y2_R2, 'r');

xline(ax2,40,':');

ax2.YAxis(1).Visible = 'off';

ax2.Box = 'off';

xlim(ax2,[40 50])

linkaxes([ax1 ax2], 'y')

You see, the y1 data has lost the link to the left y-axis. Is there any way to maintain the data link for both y axes?

Thank you for your help!

Here's an alternative approach:

x_R1 = 0:10;

y1_R1 = 0:10;

y2_R1 = 100:-1:90;

x_R2 = 40:50;

y1_R2 = 10:20;

y2_R2 = 90:-1:80;

t = tiledlayout(1, 2);

yyaxis(nexttile(1), 'left')

plot(nexttile(1),x_R1,y1_R1, 'b')

yyaxis(nexttile(1), 'right')

plot(nexttile(1), x_R1,y2_R1, 'r');

yyaxis(nexttile(2), 'left')

plot(nexttile(2),x_R2,y1_R2, 'b')

yyaxis(nexttile(2), 'right')

plot(nexttile(2), x_R2,y2_R2, 'r');

YLmin = min([nexttile(1).YAxis(1).Limits, nexttile(2).YAxis(1).Limits]);

YLmax = max([nexttile(1).YAxis(1).Limits, nexttile(2).YAxis(1).Limits]);

YRmin = min([nexttile(1).YAxis(2).Limits, nexttile(2).YAxis(2).Limits]);

YRmax = max([nexttile(1).YAxis(2).Limits, nexttile(2).YAxis(2).Limits]);

yyaxis(nexttile(1), 'left')

ylim([YLmin YLmax])

yyaxis(nexttile(1), 'right')

ylim([YRmin YRmax])

yyaxis(nexttile(2), 'left')

ylim([YLmin YLmax])

yyaxis(nexttile(2), 'right')

ylim([YRmin YRmax])

Or with your original code:

x_R1 = 0:10;

y1_R1 = 0:10;

y2_R1 = 100:-1:90;

x_R2 = 40:50;

y1_R2 = 10:20;

y2_R2 = 90:-1:80;

figure

t = tiledlayout(1,2,'TileSpacing','tight');

bgAx = axes(t,'XTick',[],'YTick',[],'Box','off');

bgAx.Layout.TileSpan = [1 2];

ax1 = axes(t);

plot(ax1,x_R1,y1_R1, 'b')

yyaxis right

plot(ax1, x_R1,y2_R1, 'r');

ax1.YAxis(2).Visible = 'off';

xline(ax1,10,':');

ax1.Box = 'off';

xlim(ax1,[0 10])

ax2 = axes(t);

ax2.Layout.Tile = 2;

plot(ax2,x_R2,y1_R2, 'b')

yyaxis right

plot(ax2, x_R2,y2_R2, 'r');

xline(ax2,40,':');

ax2.YAxis(1).Visible = 'off';

ax2.Box = 'off';

xlim(ax2,[40 50])

linkaxes([ax1 ax2], 'y')

YLmin = min([ax1.YAxis(1).Limits, ax2.YAxis(1).Limits]);

YLmax = max([ax1.YAxis(1).Limits, ax2.YAxis(1).Limits]);

YRmin = min([ax1.YAxis(2).Limits, ax2.YAxis(2).Limits]);

YRmax = max([ax1.YAxis(2).Limits, ax2.YAxis(2).Limits]);

yyaxis(ax1, 'left')

ylim([YLmin YLmax])

yyaxis(ax1, 'right')

ylim([YRmin YRmax])

yyaxis(ax2, 'left')

ylim([YLmin YLmax])

yyaxis(ax2, 'right')

ylim([YRmin YRmax])

Hello Antonio,

I understand that you are trying to plot 2 sets of data on the same x-axis, but the x-axis was discontinued. There were 2 ranges, R1 and R2 respectively, and you were trying to plot y1 on the left axis and y2 on the right axis for both the ranges, but you were unable to do.

To achieve this, you have to calculate minimum and maximum limits for both y1 and y2(which are YLMin and YLMax for y1 and YRMin and YRMax for y2 in his code). And then, just use the "yyaxis" function, to create a chart with two y axes and then add all 4 limits which were calculated to them.

Below is the code for the same:

YLmin = min([nexttile(1).YAxis(1).Limits, nexttile(2).YAxis(1).Limits]);
YLmax = max([nexttile(1).YAxis(1).Limits, nexttile(2).YAxis(1).Limits]);
YRmin = min([nexttile(1).YAxis(2).Limits, nexttile(2).YAxis(2).Limits]);
YRmax = max([nexttile(1).YAxis(2).Limits, nexttile(2).YAxis(2).Limits]);
yyaxis(nexttile(1), 'left')
ylim([YLmin YLmax])
yyaxis(nexttile(1), 'right')
ylim([YRmin YRmax])
yyaxis(nexttile(2), 'left')
ylim([YLmin YLmax])
yyaxis(nexttile(2), 'right')
ylim([YRmin YRmax])
