Module Version: 0.022
Hypatia::Chart::Clicker::Bubble - Line Charts with Hypatia and Chart::Clicker

version 0.022

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.

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.
