#Plot lines matlab line style code#
The code below generates two linear curves and edits the display of the graphs by altering the attributes of the chart line object. 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. 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() If either x or y, or both are matrices, then line draws multiple lines. The limit values for the plots can be imposed on the axes using the command ‘axis’. Description example line (x,y) plots a line in the current axes using the data in vectors x and y. 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. Use the hold on command to plot the two lines separately. Return the two Line objects as an output argument from the plot function and then set the LineWidth property for each. 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. To plot two lines with different line widths, you can use either of these approaches. See Also line, plot, surface, patch, Axes LineStyleOrder propert.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.

See the ColorSpec for more information on color.Įxamples Plot the sine function over three different ranges using different line styles, colors, and markers:Ĭreate a plot illustrating how to set line graphics properties: This is useful if you want to specific a color that is not in the list by using RGB values. In addition, you can specify the LineStyle, Color, and Marker properties instead of using the symbol string. MarkerSize - specifies the size of the marker in points.MarkerFaceColor - specifies the color of the face of filled markers.MarkerEdgeColor - specifies the color of the marker or the edge color forfilled markers (circle, square, diamond, pentagram, hexagram, and the four triangles).LineWidth - specifies the width (in points) of the line.Related Properties When using the plot and plot3 functions, you can also specify other characteristics of lines using graphics properties: Specify these symbols (in any order) as a quoted string after the data arguments. The following tables list the symbols you use to define the line style, color, and marker. If you specify a marker, but no a linesytle, MATLAB plots only the markers.
), colored red ( r), and places circular markers ( o) at the data points.
