Hypatia::Chart::Clicker::Bubble - Line Charts with Hypatia and Chart::Clicker


version 0.026


This module extends Hypatia::Chart::Clicker. The graph method (also known as the chart method) returns the Chart::Clicker object built from the relevant data and options provided.



The required column types are x, y, and size. Each of the values for this attribute may be either a string (indicating one column) or an array reference of strings (indicating several columns). If y and size are array references, then they must be the same size. If x is an array reference, then it also must be the same size as y and size (and in this case, each x column will serve as x-axis values corresponding to the y and size columns). Otherwise, if x is a string, then the single x column will serve as a common set of x-values for all y and size values.

Of course, since size represents size values for the given data set(s), please make sure that the data stored in any size columns contains nonnegative values.

If this column isn't provided, then Hypatia will do its best job to guess which column names of your data correspond to which types, as follows:

1. If there are three columns, then they'll be assigned to x, y, and size (respectively). =item 2. Otherwise, if the number of columns is a multiple of 3, then the corresponding types will be
        x, y, size, x, y, size,..., x, y, size

(ie each consecutive triple will be assigned to x, y, and size, respectively).

3. If the number of columns is odd, larger than 3, but not divisible by 3, then the first column will be assigned to type x, and the remaining columns will be paired off as types:
        y, size, y, size,..., y, size
4. If none of the above are the case, then an error is thrown.


chart([$data]), a.k.a graph([$data])

This method returns the relevant Chart::Clicker object. If neither the dbi nor the input_data attributes have been set, then you can input your data as an argument here.
