bubblesize

Set minimum and maximum bubble sizes in points

Syntax

bubblesize(sizerange)

bubblesize(ax,sizerange)

sz = bubblesize

sz = bubblesize(ax)

Description

bubblesize(sizerange) sets the size of the smallest and largest bubble for bubble charts in the current axes. Specify sizerange as a two-element vector containing the smallest and largest diameters in points, where 1 point = 1/72 inch.

bubblesize(ax,sizerange) sets the bubble sizes in the axes specified by ax.

sz = bubblesize returns the size range for the current axes as a two-element vector containing the diameters of the smallest and largest bubbles in points.

sz = bubblesize(ax) returns the size range for the axes specified by ax.

Examples

Change Bubble Sizes

Create a bubble chart with a legend.

x = 1:10;
y = [4 7 10 7 3 6 5 1 9 7];
sz = [5 1 14 6 9 12 15 20 8 2];
bubblechart(x,y,sz);
bubblelegend('Population','Location','northeastoutside')

Get the current range of bubble sizes.

bubblesize

ans = 1×2

     3    50

Change the bubble sizes so that they are between 5 and 20 points in diameter. The bubble legend automatically updates to reflect the new bubble sizes.

bubblesize([5 20])

Change Bubble Sizes for Specific Axes

Create two sets of data, then create a tiled chart layout containing two bubble charts.

% Create two sets of data
x1 = 1:10;
x2 = 1:50;
y1 = rand(1,10);
y2 = rand(1,50);
sz1 = randperm(10,10);
sz2 = randperm(50,50);

% Create tiled chart layout
t = tiledlayout(1,2);

% Create bubble chart in first tile
ax1 = nexttile;
bubblechart(x1,y1,sz1)

% Create bubble chart in first tile
ax2 = nexttile;
bubblechart(x2,y2,sz2)

Query the range of bubble sizes in the right chart by passing ax2 to the bubblesize function.

bubblesize(ax2)

ans = 1×2

     3    50

Change the bubble sizes in the right chart so that they range between 5 and 15 points in diameter.

bubblesize(ax2,[5 15])

Input Arguments

sizerange — Size range

two-element vector

Size range, specified as a two-element vector containing positive numbers, where the second number is greater than the first. The numbers specify the smallest and largest bubble sizes in points, where 1 point = 1/72 inch.

By default, bubble charts use a size range of [3 50].

Example: bubblesize([20 70]) sets the smallest bubble size to 20 points and the largest bubble size to 70 points.

ax — Target axes

Axes object | PolarAxes object | GeographicAxes object

Target axes, specified as an Axes, PolarAxes, or GeographicAxes object.
