#Matlab line style for multiple lines code#
The code below generates two linear curves and edits the display of the graphs by altering the attributes of the chart line object. Some functions like ot support passing Line properties as keyword arguments. 3, 1 would be 3pt long lines separated by 1pt spaces.
#Matlab line style for multiple lines series#
The dash sequence is a series of on/off lengths in points, e.g. The generated plot gets assigned to a chart line object, and its display gets customized by altering the attributes from the storing chart line object. The dashing of a line is controlled via a dash sequence.
Matlab extends its feature in 2D line plots to customize the plot presentation through the execution even after the plot is generated. Plot(x,y1,x,y2,'-o','MarkerIndices',1:1:50)Ĭustomizing the presentation of the lines after the creation of the plot. The below example generates 2 line plots, and we highlight one plot with the marker symbol ‘-o’.
In the case of a graph containing lines more than three and having overlapped presentation, it helps to determine which data point belongs to which plot. Markers help point out distinct data points on the plotted line to determine the exact values calculated from the function. The code snippet below generates six lines for the function defined by ‘y’, the looping variable’ x’ function.ĭisplaying markers for specific data points for the lines. This can also be achieved by calling the plot function in a loop where the plotting function can be defined as a function of the looping variable. Matlab enables users to plot more than two lines in a single plane. The code displays the data mapping each line to its corresponding plotting function. Including legend to distinguish the line plots: Application of the attribute ‘legend’ adds information to the plot to guide the user in identifying the lines with respect to their plotting functions. %Placing the second line plot in the second cell of the frame %Placing the first line plot in the first cell of the frame The below example presents 2 line plots generated from one single execution of the program with two different sets of axes. Arranging multiple line plots in different subplots: Matlab supports presenting the line plots generated in a single execution with a distinct set of axes. %The minimum value of the y-axis gets updated to -0.1 and the maximum value for the x-axis is updated to 12. Syntax to incorporate axes limit: axis ( )Ĭode: plot(x, y1,x,y2), axis()
The limit values for the plots can be imposed on the axes using the command ‘axis’. Plot(x, y1,x,y2), xlabel('x-axis'), ylabel('y-axis'), title('Graph customisation'), %Adding x-label, y-label and title to the resultant plot The example defined below demonstrates the process of customization of the presentation of the graph by modifying the attributes given above. Axis square: A set of square plots can be generated. Axis equal: The plots can be created with a common scale factor and spaces for both axis.į. Grid on: Makes the grid lines visible for the graph.Į. The customization of the lines drawn from single plot functions can be achieved by altering any of the attributes or any combination of the attributes described below:Ĭ. Tell us here how you customize your visualizations to convey your ideas as clearly as possible.The resultant plot consists of 2 sinusoidal line curves, ‘y1’ and ‘y2′, having two different sets of values’,x1′ and ‘x2’, but share a common x-y plane. Line 1 is green and line 40 is red.Īs a bonus, take a look at Loren's blog on Plotting with Style to learn about other ways to customize the line style. Since I appropriately chose the number of colors to be the same as the number of lines, the colormap scale corresponds to Instead, I can use the color matrix that I just created and use that in my color bar. I can simply add the default legend:īut this is quite impractical. When I have this many lines, I often wonder what the best way to put a legend is. (Be sure to use hold all to preserve the color order.) Now, my subsequent plots will follow the new color order. Or set it as the new ColorOrder property of an axes. I can either index into this color matrix and use it as my Color property for plot: Daniel's varycolor will give you that color set with a single command. Have you ever had to plot many lines on a single graph and you had to construct additional set of colors to augment the 8īuilt-in colors? You may have to come up with a good set of colors that span a wide range of the spectrum. Jiro's pick this week is VARYCOLOR by Daniel Helmick.
