bar3 Axis labels don't reflect real data
显示 更早的评论
I'm trying to plot Z bars against X and Y with more than a few data points. I would like the x and y axis labels to be the real x and y data. Using the example code below, each x and y bar should correspond to its X and Y axis data - but they don't. Plus, the tables change as I re-size the chart. I'm sure I'm just missing something simple.
surf() plots the correct axis, but the data points are not really connected in real life, so that plot is not really appropriate.
Here's and example:
format shortg
xAxis = sort(10*rand(20,1));
sprintf('XMin: %5f xMax: %5f', [min(xAxis) max(xAxis)])
yAxis = sort(30*rand(30,1));
sprintf('yMin: %5f yMax: %5f', [min(yAxis) max(yAxis)])
bar3(rand(20,30));
set(gca,'XTickLabel',xAxis)
set(gca,'YTickLabel',yAxis)

Try scaling the tick marks based on the limits you've defined:
format shortg
xAxis = sort(10*rand(20,1));
sprintf('XMin: %5f xMax: %5f', [min(xAxis) max(xAxis)])
yAxis = sort(30*rand(30,1));
sprintf('yMin: %5f yMax: %5f', [min(yAxis) max(yAxis)])
bar3(rand(20,30));
tick = get(gca,{'XTick','YTick'});
x = linspace(min(xAxis),max(xAxis),length(tick{1}));
y = linspace(min(yAxis),max(yAxis),length(tick{2}));
set(gca,'XTickLabel',x)
set(gca,'YTickLabel',y)
