Plot graph using dots and colormap to show the frequency

Hi, I have a set of data (x and y) and I would like to plot a graph using dots/scatter and a colormap to indicate the frequency/intensity of it happening. I used the code as shown below but I do not want the graph to be plotted in tiles because it would not be presentable in a semilog scale graph. So, instead of using tile, I would like the graph to be plotted in dots instead and the colormap to show the intensity. Thank you very much in advance.
hist=histogram2(x,y,[150,200],'DisplayStyle','tile');
c = colorbar;
colormap ('jet');

To plot a graph using dots/scatter and a colormap to indicate the frequency/intensity of the data points, you can use the scatter function in MATLAB. Here's an example of how you can modify your code:
% Sample data
x = [1, 2, 3, 4, 5];
y = [10, 20, 30, 40, 50];
intensity = [2, 5, 3, 7, 10]; % Intensity values for colormap
% Plotting with scatter and colormap
figure;
scatter(x, y, [], intensity, 'filled');
colormap('jet'); % Choose your desired colormap
colorbar; % Add a colorbar to show the intensity scale
% Additional plot settings
xlabel('X');
ylabel('Y');
title('Scatter Plot with Colormap');
Hope this helps.
