Is it possible to specify certain plotting properties when using plotyy()?
Posted:

I have an unusual set of data that I would like to display using the plotyy() function. Data Set A has pairs of values that need to be connected by a line, but each pair should appear separate from all other pairs. Data Set B consists of values that were collected in between each pair of values from Data Set A. Currently, I have had no problem using the regular plot() function to generate a reasonable plot, although the scale of Set B is not shown. For reference, here is the code for the singleYaxis plot I generate:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
x_set1 = [1 2]; x_set2 = [3 4]; x_set3 = [5 6]; x_set4 = [7 8]; x_set5 = [9 10];
S1_data_subset1 = [0.18 0.18]; S1_data_subset2 = [0.42 0.38]; S1_data_subset3 = [0.42 0.44]; S1_data_subset4 = [0.42 0.48]; S1_data_subset5 = [0.60 0.72];
x_learning = [1.5 3.5 5.5 7.5 9.5]; S1_learning = [19 1 1 9 1]; figure; plot(x_set1, S1_data_subset1,'ko','LineWidth',2); hold on; plot(x_set2, S1_data_subset2,'ko','LineWidth',2); hold on; plot(x_set3, S1_data_subset3,'ko','LineWidth',2); hold on; plot(x_set4, S1_data_subset4,'ko','LineWidth',2); hold on; plot(x_set5, S1_data_subset5,'ko','LineWidth',2); hold on; plot(x_learning, S1_learning,'bo','LineWidth',2);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
However, now I am trying to use the plotyy() function so that Data Set B?s value will have some meaning, and ideally so that I will be able to scale the 2 y axes so that I can match up their 0 values to be the same. However, I?m having difficulty with using plotyy(); the following code:
x_set1 = [1 2]; x_set2 = [3 4]; x_set3 = [5 6]; x_set4 = [7 8]; x_set5 = [9 10]; S1_data_subset1 = [0.18 0.18]; S1_data_subset2 = [0.42 0.38]; S1_data_subset3 = [0.42 0.44]; S1_data_subset4 = [0.42 0.48]; S1_data_subset5 = [0.60 0.72]; x_learning = [1.5 3.5 5.5 7.5 9.5]; S1_learning = [19 1 1 9 1]; x_learning1 = [1.5]; x_learning2 = [3.5]; x_learning3 = [5.5]; x_learning4 = [7.5]; x_learning5 = [9.5]; S1_learning1 = [19]; S1_learning2 = [1]; S1_learning3 = [1]; S1_learning4 = [9]; S1_learning5 = [1]; [AX1,H1,H2] = plotyy(x_set1,S1_data_subset1,x_learning1,S1_learning1); hold on; [AX2,H3,H4] = plotyy(x_set2,S1_data_subset2,x_learning2,S1_learning2); hold on; [AX3,H5,H6] = plotyy(x_set3,S1_data_subset3,x_learning3,S1_learning3); hold on; [AX4,H7,H8] = plotyy(x_set4,S1_data_subset4,x_learning4,S1_learning4); hold on; [AX5,H9,H10] = plotyy(x_set5,S1_data_subset5,x_learning5,S1_learning5);
? generates a figure that is problematic because: ~ there are 2 sets of x axis labels overlaid and it is a mess ~ the second Y axis has multiple values overlaid at each tick mark ~ the Edit >Axes Properties dialog box only allows me access to the first (and already correct) Y axis ~ I can?t seem to specify the marker types and sizes for the 2 data sets
I have tried to manage the handle properties, but these don?t appear to be able to change the marker size & line style properties that I need to modify.
Does anyone have suggestions about how to solve the above issues? Thanks in advance for your help!
