![]() Use a dashed line style for the stem, set the marker symbols to stars, and set the color to magenta. Here we discuss an introduction to Matlab Plot Colors, along with color code table and respective examples. Create a 3-D stem plot of cosine values between - and. There could be instances when we have to plot multiple functions in a single plot, in such cases, colors become very handy to differentiate between different functions. MATLAB can be used to plot our data for visualizing and intuitively understanding it. figure X linspace (-pi,pi,40) Z cos (X) stem3 (Z, '-m') To specify only two of the three LineSpec options, omit the third option from the character vector. The alternative is to manually draw the lines for each marker after scatter. Create a 3-D stem plot of cosine values between - and. ![]() Observe in the output that we have obtained a scatter plot of red color, as passed by us in the input argument. hScscatter3 (Vdotr, Vdota, conv, 60, conv, 'filled') colormap (cool) that will put the colors on the markers but leaves the stems in the default color - you can change that to black, say, but not variable to match. For horizontal stem plots, the locs are y positions, and the heads are x values. For vertical stem plots (the default), the locs are x positions, and the heads are y values. Observe in the code that we have passed pre-defined color code for red as an argument (Please refer to the table at the end of the article for pre-defined color codes) A stem plot draws lines perpendicular to a baseline at each location locs from the baseline to heads, and places a marker there. For this example, we will scatter plot of red color
