Hi Bhaskar,
From the given description, it seems like you want to add whiskers to a custom value of IQR instead of the default. As per my understanding, this is not directly possible with the 'boxchart' function. Here is a possible workaround that adds the custom whiskers to the initial plot:
% Assuming that data stores your data
bc = boxchart(data);
% Adding custom whiskers:
lowerPercentile = 0.3; % 30th percentile
upperPercentile = 0.7; % 70th percentile
% Calculate custom percentiles
customBounds = quantile(data, [lowerPercentile, upperPercentile]);
ax = gca;
hold on;
xPos = 1;
yLower = customBounds(1);
yUpper = customBounds(2);
% Plot lines for custom percentiles
% Adjust x-coordinates based on your data structure and boxchart layout
plot(ax, [xPos-0.4, xPos+0.4], [yLower, yLower], '--r');
plot(ax, [xPos-0.4, xPos+0.4], [yUpper, yUpper], '--r');
hold off;
This script calculates and plots lines representing custom whiskers at the 30th and 70th percentiles. It is important to note that this approach visually marks the custom whiskers without altering the box itself.
Hope this helps!
