![]() Special cases: vertical lines (minf) and parallel lines (m1 m2) First find slopes and intercepts for both line segments. Then see if that x value is in the necessary range. Note: The term marker is generally used, not for the graph line, the plot, but for the pointers on the graph line that scopes and also MATLAB allows to put, to read a particular (x,y). First Algorithm Using equation y mx+b, solve for x assuming 2 lines intersect. But no one uses what is otherwise a rather long Java-like expression In this paper, an improved Backward-Forward Sweep (BFS) technique for power flow analysis is achieved by breaking the conventional solution strategy into a number of logical steps (Matlab sub-functions) that simplifies the problem of node tracing and eliminates the need for sequential node numbering. The figure handle hf1 could still be used to change trace properties, because as the container to the plot, has as children property the handle to the plot. If you do not update Pin_dBm and-or Pout_Meas_dbm the next plot with different properties may be identical or similar and overlap the previous trace. Can anyone explain why this is happening. Unlike the plot function, line adds the line to the current axes without deleting other graphics objects or resetting axes properties. If either x or y, or both are matrices, then line draws multiple lines. As far as I can tell, only ':' is being acknowledged and shown everything else just uses a solid line regardless of what I put in. Description example line (x,y) plots a line in the current axes using the data in vectors x and y. ![]() However, most of the style changes are being ignored by matlab for no apparent reason. ![]() Also, you can plot expressions or functions over specific intervals. You can plot the data in a 2-D or 3-D view using either a linear or a logarithmic scale. Line plots are a useful way to compare sets of data or track changes over time. Now you tell the graph container, the figure with handle hf1 not to remove the 1st trace regardless of what you plot next: hold(ax1,'on')Īnd now, with a for loop or one by one, or in any other way you choose, you can add more traces onto same figures changing the properties you choose using a different plot handle hp2=plot(Pin_dBm2,Pout_Meas_dbm2)Īnd as you mention in your question you can send the same variable updated with different input data or file update_Pin_dBm I am attempting to make lines more easily distinguishable by changing the line styes. Line plots, log plots, and function plots. The figure is the frame containing traces.īut it's good practice to number figures figure(n) as soon as generated, it helps reading code if later on someone has to findout what figure handle belongs to what figure. The toolbox also provides functions to generate swept-frequency waveforms. ), colored red ( r ), and places circular markers ( o) at the data points. For example, plot (x,y,'-.ro') plots y versus x using a dash-dot line (. Hf1 is the figure handle, not the trace or curve or graph handle. An optional width parameter specifies a fractional multiple of 2 at which. LineSpec is an argument to plotting functions, such as plot, that defines three components used to specify lines in MATLAB: Line style. To grab the plot handle you have to plot like this hf1=figure(1) To change trace (or marker) properties you have to use the plot handle, not the figure handle, to change line properties like LineWidth and Color.
