tilerowcol

Row and column numbers in tiled chart layout

    Description

    example

    [row,col] = tilerowcol(t,tnum) returns the row and column numbers for the specified tile number in the tiled chart layout t. Specify tnum as a scalar tile number or an array of tile numbers.

    This function does not support layouts that use the "flow" tile arrangement.

    example

    [row,col] = tilerowcol(obj) returns the row and column numbers of the specified object in a tiled chart layout. For example, you can use this syntax to get the rows and columns for a specified axes object.

    Examples

    Create a 2-by-2 tiled chart layout containing four plots.

    t = tiledlayout(2,2);
    
    nexttile
    plot([1 2 3 4])
    
    nexttile
    scatter(1:7,[10 13 5 33 7 12 9])
    
    nexttile
    stairs(1:10)
    
    nexttile
    bar(1:5)

    Figure contains 4 axes objects. Axes object 1 contains an object of type line. Axes object 2 contains an object of type scatter. Axes object 3 contains an object of type stair. Axes object 4 contains an object of type bar.

    Get the row and column numbers for the third tile.

    [row,col] = tilerowcol(t,3)
    row = 2
    
    col = 1
    

    Get the row and column numbers for all the tiles.

    [row,col] = tilerowcol(t,[1 2 3 4])
    row = 1×4
    
         1     1     2     2
    
    
    col = 1×4
    
         1     2     1     2
    
    

    Create a 2-by-2 tiled chart layout containing four plots.

    t = tiledlayout(2,2);
    
    nexttile
    plot([1 2 3 4])
    
    nexttile
    scatter(1:7,[10 13 5 33 7 12 9])
    
    nexttile
    stairs(1:10)
    
    nexttile
    bar(1:5)

    Figure contains 4 axes objects. Axes object 1 contains an object of type line. Axes object 2 contains an object of type scatter. Axes object 3 contains an object of type stair. Axes object 4 contains an object of type bar.

    The Children property of the TiledChartLayout object contains all the top-level objects in the layout. In this case, the top-level objects are axes. Note that the objects in the Children property are in the opposite order of their creation. To get the rows and columns in the order of creation, call the flipud function and pass the reordered array to the tilerowcol function.

    [row,col] = tilerowcol(flipud(t.Children))
    row = 4×1
    
         1
         1
         2
         2
    
    
    col = 4×1
    
         1
         2
         1
         2
    
    

    Create a 3-by-3 tiled chart layout containing three plots in the first row. Then create an axes object that spans across the remaining empty tiles (a 2-by-3 region). Create a bar chart in the spanned axes.

    tiledlayout(3,3)
    
    nexttile
    plot([1 2 3 4])
    
    nexttile
    plot([4 3 2 1])
    
    nexttile
    stairs(1:10)
    
    % Create spanned axes and bar chart
    spax = nexttile([2 3]);
    bar(spax,1:10)

    Figure contains 4 axes objects. Axes object 1 contains an object of type line. Axes object 2 contains an object of type line. Axes object 3 contains an object of type stair. Axes object 4 contains an object of type bar.

    Get the row and column numbers for the spanned axes. tilerowcol returns the numbers of the row and column at the upper-left corner of the spanned axes, not the entire set of spanned rows and columns.

    [r,c] = tilerowcol(spax)
    r = 2
    
    c = 1
    

    You can use the tilerowcol function to customize the axes in a specific row or column of a tiled chart layout. In this example, show the y-axis labels in the first column only, and show the x-axis labels in the bottom row only.

    Create a 4-by-4 tiled chart layout containing 16 plots. Pass the Children property of the TiledChartLayout object to the tilerowcol function to get the rows and columns of all the tiles. Remove the y-axis tick labels from all the axes in the columns that have an index greater than 1. Remove the x-axis tick labels from all the axes that are not in the last row. Then add an overall title to the layout.

    t = tiledlayout(4,4,TileSpacing="compact");
    for i=1:16
        nexttile
        plot(rand(10,3))
    end
    
    % Remove select y- and x-axis tick labels
    [row,col] = tilerowcol(t.Children);
    yticklabels(t.Children(col>1),"")
    xticklabels(t.Children(row<t.GridSize(1)),"") 
    title(t,"Tiling of 16 Plots")

    Figure contains 16 axes objects. Axes object 1 contains 3 objects of type line. Axes object 2 contains 3 objects of type line. Axes object 3 contains 3 objects of type line. Axes object 4 contains 3 objects of type line. Axes object 5 contains 3 objects of type line. Axes object 6 contains 3 objects of type line. Axes object 7 contains 3 objects of type line. Axes object 8 contains 3 objects of type line. Axes object 9 contains 3 objects of type line. Axes object 10 contains 3 objects of type line. Axes object 11 contains 3 objects of type line. Axes object 12 contains 3 objects of type line. Axes object 13 contains 3 objects of type line. Axes object 14 contains 3 objects of type line. Axes object 15 contains 3 objects of type line. Axes object 16 contains 3 objects of type line.

    Input Arguments

    collapse all

    Tiled chart layout containing the tiles you want to locate. Use the tiledlayout function to create the TiledChartLayout object.

    The TileArrangement property of the TiledChartLayout object must be set to "fixed", which is the default value when you call tiledlayout(m,n) to create a fixed number of tiles.

    Tile numbers, specified as a scalar, vector, or array of positive integer values. If you specify a number that does not correspond to a tile number, tilerowcol returns NaN for that number.

    Graphics object or an array of graphics objects that are children of a tiled chart layout. The types of objects you can specify include:

    • Axes, such as Axes, PolarAxes, or GeographicAxes objects

    • Standalone visualizations, such as heatmap charts

    • Legends

    • Colorbars

    • TiledChartLayout objects that are nested within the tiles of a tiled chart layout

    If a specified object is in one of the "north", "south", "east", or "west" tiles, tilenum returns NaN for that object.

    Output Arguments

    collapse all

    Row and column numbers of the tiled chart layout, returned as two scalars, two vectors, two or two arrays containing the row and column indices of the tiled chart layout. If you query multiple tile numbers (or multiple objects) by specifying a vector or an array, tilerowcol returns the output as vectors or arrays of the same size.

    tilerowcol returns NaN values if tnum does not correspond to a tile number, or if obj is a graphics objects in one of the "north", "south", "east", or "west" tiles.
