Region-zoom interaction

expand all in page

Description

A region-zoom interaction allows you to zoom into a rectangular region of a chart in a 2-D view without having to select any buttons in the axes toolbar. To enable region zooming, set the Interactions property of the axes to a regionZoomInteraction object. When this interaction is enabled, you can zoom into a region by dragging within the chart.

To enable multiple interactions, set the Interactions property to an array of objects.

Creation

Syntax

rz = regionZoomInteraction
rz = regionZoomInteraction('Dimensions',d)

Description

rz = regionZoomInteraction creates a region-zoom interaction object.

example

rz = regionZoomInteraction('Dimensions',d) sets the Dimensions property. Use this property to constrain zooming to specific dimensions. For example, rz = regionZoomInteraction('Dimensions','x') constrains zooming to the x-dimension.

Properties

Dimensions to allow zooming, specified as one of these values:

  • 'xyz' — Allows zooming in all dimensions.

  • 'xy' — Allows zooming in the x and y dimensions only.

  • 'yz' — Allows zooming in the y and z dimensions only.

  • 'xz' — Allows zooming in the x and z dimensions only.

  • 'x' — Allows zooming in the x dimension only.

  • 'y' — Allows zooming in the y dimension only.

  • 'z' — Allows zooming in the z dimension only.

Open Script

Create a plot of fifty random numbers. Get the current axes, and replace the default interactions with the region-zoom and data tip interactions. Then hover over the plotted points to display data tips. Drag to zoom into a region of the plot.

plot(rand(1,50),'-o')
ax = gca;
ax.Interactions = [regionZoomInteraction dataTipInteraction];

Open Script

Create a scatter plot of normally distributed random data. Replace the default set of interactions with a region-zoom interaction that operates only in the x-dimension. Then drag within the plot to zoom into a region of interest.

x = linspace(-1,1,1000);
y = randn(1,1000);
scatter(x,y,'.')
ax = gca;
ax.Interactions = regionZoomInteraction('Dimensions','x');

Limitations

The region-zoom interaction is not supported for charts in a 3-D view.

Tips

In most cases, the axes have a default set of interactions which depend on the type of chart you are displaying. You can replace the default set with a new set of interactions, but you cannot access or modify any of the interactions in the default set.
