Hypatia::Chart::Clicker::Bubble - Line Charts with Hypatia and Chart::Clicker
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
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
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
size (and in this case, each
x column will serve as x-axis values corresponding to the
size columns). Otherwise, if
x is a string, then the single
x column will serve as a common set of x-values for all
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
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
- 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.
