Slope chart
Updated a month ago to v14.0.2 by Flourish team
How to use this template
Slope chart
A simple charting template to plot the differences between two values. Useful to compare the difference in population, income or wealth.
Data requirements
Each row after the header row is one slope. There should be a column for the name and two columns for the values. The values should be of the same data type (eg. votes, income, population).
Credits and feedback
Created by Flourish. Sample data is from the World Bank illustrating exports of goods and services as percentage of GDP per country. The slope with an activated filter uses data from the MIT Election Lab. Want to see additional features? Let us know at support@flourish.studio.
API information
This section documents API usage specific to this template, so for an introduction we suggest you refer to the generic API documentation instead.
template: @flourish/slope-chart
version: 14
Template data
There are three different formats in which you can supply data to this template. The most convenient for you to use likely depends on the source of your data, as described below.
1. Array of arrays, and a bindings object
You can supply arrays of arrays to opts.data, which might look
like:
{
data: {
data: [
[ "DataColumn1Value1", "DataColumn2Value1",
[ "DataColumn1Value2", "DataColumn2Value2",
[ "DataColumn1Value3", "DataColumn2Value3",
...
]
}
}
where each array of arrays represents the rows in a data sheet.
To tell the API how the values from each column should be
associated with the keys that the template is expecting, you must also supply
an object attached to opts.bindings. (The meanings of the
keys in the bindings object are documented
below.) The minimal bindings you can
supply for this template are as shown in this example:
{
template: "@flourish/slope-chart",
version: "14",
bindings: {
data: {
id: 0, // index of a column in your data
}
},
data: {
data: [
[ "DataColumn1Value1", "DataColumn2Value1",
[ "DataColumn1Value2", "DataColumn2Value2",
[ "DataColumn1Value3", "DataColumn2Value3",
...
]
}
}
All possible bindings that you can supply are shown in this example:
{
template: "@flourish/slope-chart",
version: "14",
bindings: {
data: {
id: 0, // index of a column in your data
values: [1, 2, ...], // index(es) of column(s) in your data
line_thickness: 3, // index of a column in your data
filter: 4, // index of a column in your data
color_category: 5, // index of a column in your data
facet: 6, // index of a column in your data
metadata: [7, 8, ...], // index(es) of column(s) in your data
}
},
data: {
data: [
[ "DataColumn1Value1", "DataColumn2Value1",
[ "DataColumn1Value2", "DataColumn2Value2",
[ "DataColumn1Value3", "DataColumn2Value3",
...
]
}
}
2. Array of objects with arbitrary keys, and a bindings object
This format is most likely useful when you have data from an external source,
such as CSV data loaded from d3-dsv.
You should supply this attached to the opts.data, which might look
like:
{
data: [
{ "DataHeader1": ..., "DataHeader2": ..., ... },
{ "DataHeader1": ..., "DataHeader2": ..., ... },
{ "DataHeader1": ..., "DataHeader2": ..., ... },
...
]
}
... but with the keys being the column headers from your
source data instead. You must also supply an object attached to
opts.bindings. The minimal bindings you can
supply for this template are as shown in this example:
{
template: "@flourish/slope-chart",
version: "14",
bindings: {
data: {
id: "DataHeader1",
}
},
data: {
data: [
{ "DataHeader1": ..., "DataHeader2": ..., ... },
{ "DataHeader1": ..., "DataHeader2": ..., ... },
{ "DataHeader1": ..., "DataHeader2": ..., ... },
...
]
}
}
All possible bindings that you can supply are shown in this example:
{
template: "@flourish/slope-chart",
version: "14",
bindings: {
data: {
id: "DataHeader1",
values: ["DataHeader2", "DataHeader3", ...],
line_thickness: "DataHeader4",
filter: "DataHeader5",
color_category: "DataHeader6",
facet: "DataHeader7",
metadata: ["DataHeader8", "DataHeader9", ...],
}
},
data: {
data: [
{ "DataHeader1": ..., "DataHeader2": ..., ... },
{ "DataHeader1": ..., "DataHeader2": ..., ... },
{ "DataHeader1": ..., "DataHeader2": ..., ... },
...
]
}
}
(As before, the keys containing "Header" would be replaced by column names from your data source.)
3. Array of objects with template-defined keys
There is an alternative format you can use, which is likely to be easier to
use if your data is not from a spreadsheet source. With this alternative format
you supply your data to the template as
an array of objects, attached to opts.data, where the keys must
be those used by the template, as documented below. In this case
there is no need to supply a bindings object, since the key names are already
those expected by the template. The required properties in the data
object are as follows (scroll down for a
description of what each property is):
{
template: "@flourish/slope-chart",
version: "14",
data: {
data: [
{
id: ...,
values: [...],
metadata: [...]
},
...
]
},
...
}
And the full list of all possible properties is as follows:
{
template: "@flourish/slope-chart",
version: "14",
data: {
data: [
{
id: ...,
values: [...],
line_thickness: ...,
filter: ...,
color_category: ...,
facet: ...,
metadata: [...]
},
...
]
},
...
}
Meanings of the template data keys:
- data.id: The name of the data series (eg. voting district, data mode)
- data.values: Values for that data series (eg. % of votes).
- data.line_thickness: Values for the thickness of line
- data.filter: filter string, number, datetime
- data.color_category: color_category
- data.facet: facet
- data.metadata: One or more columns of information (text, <a href="https://help.flourish.studio/article/46-how-to-add-images-to-your-visualization">image URLs</a>, <a href="https://help.flourish.studio/article/259-how-to-embed-charts-in-your-popups-or-panels">embedded charts</a> etc) to include in custom <a href="https://help.flourish.studio/article/69-how-to-add-custom-content-to-your-popups">popups and panels</a> string, number, datetime
Template metadata
Note: metadata is optional, and the API will interpret your data for you if you do not specify it. A typical example of when specifying metadata can be useful is when column(s) in your data contain numbers or dates that you wish to format visually (e.g. to display a column containing MM/DD/YYYY dates in DD/MM/YYYY format).
This template supports an optional metadata property. metadata informs the template what type of data is in each of your columns, and how that data should be formatted visually.
You can specify metadata in one of three formats, depending on the format of opts.data.
1. Array of objects with column indexes as keys
You should supply metadata in this format when opts.data is in the previously described 'array of arrays' format. In this case, metadata should be an object with column index: column type object key/value pairs (column type objects must have type, type_id, and output_format_id keys, documented below):
{
template: "@flourish/slope-chart",
version: "14",
...
data: {
data: [
[ "DataColumn1Value1", "DataColumn2Value1",
[ "DataColumn1Value2", "DataColumn2Value2",
[ "DataColumn1Value3", "DataColumn2Value3",
...
]
},
metadata: {
data: {
0: { type: ..., type_id: ..., output_format_id: ... },
1: { type: ..., type_id: ..., output_format_id: ... },
}
},
...
}
2. Array of objects with column headers as keys
You should supply metadata in this format when opts.data is in the previously described 'array of objects with arbitrary keys' format. In this case, metadata should be an object with column header: column type object key/value pairs (column type objects must have type, type_id, and output_format_id keys, documented below):
{
template: "@flourish/slope-chart",
version: "14",
data: {
data: [
{ "DataHeader1": ..., "DataHeader2": ..., ... },
{ "DataHeader1": ..., "DataHeader2": ..., ... },
{ "DataHeader1": ..., "DataHeader2": ..., ... },
...
]
},
metadata: {
data: {
"DataHeader1": { type: ..., type_id: ..., output_format_id: ... },
"DataHeader2": { type: ..., type_id: ..., output_format_id: ... },
}
},
...
}
Column type objects:
Column type objects tell the API what type of data is in a column:
{
type: "number", // options also include 'string', and 'datetime'
type_id: "number$comma_point", // numbers in the format 13,429.17
output_format_id: "number$space_comma", // numbers in the format 13 429,17
}
For more information on valid column type values, see Recognized Type Formats.
