Malicious npm Packages Inject SSH Backdoors via Typosquatted Libraries
Socket’s threat research team has detected six malicious npm packages typosquatting popular libraries to insert SSH backdoors.
chartjs-plugin-waterfall
Advanced tools
npm install --save chartjs-plugin-waterfall
Here's what it looks like:
Just import the plugin and add it to any chart that you want to be a waterfall chart like so:
import waterFallPlugin from 'chartjs-plugin-waterfall';
var chart = new Chart(ctx, {
plugins: [waterFallPlugin]
});
See the plugins documentation for more info.
This plugin works by checking if any of your datasets contain a property called dummyStack
that is set to true.
The stack
property must be used in conjunction with dummyStack
for this plugin to work properly.
If dummyStack
is true then it hides the label, tooltip and sets the color invisible. When you use stacking with this it creates the affect
of a floating bar as shown in the image above that we can use for waterfall charts as chartjs-2 doesn't support waterfall charts
by default.
E.g:
const data = {
datasets: [
{
label: 'Closing Costs',
data: [50],
backgroundColor: '#e8cdd7',
stack: 'stack 1',
},
{
label: 'Purchase Price',
data: [700],
backgroundColor: '#d29baf',
stack: 'stack 1',
},
{
data: [200],
waterfall: {
dummyStack: true,
},
stack: 'stack 2',
},
{
label: 'Opening Loan Balance',
data: [550],
backgroundColor: '#bb6987',
stack: 'stack 2',
},
{
label: 'Initial Cash Investment',
data: [200],
backgroundColor: '#a53860',
stack: 'stack 3',
},
],
};
This dataset will give us the look in the image above.
The plugin options can be changed at 3 different levels:
globally: Chart.defaults.global.plugins.waterfall.*
per chart: options.plugins.waterfall.*
per dataset: dataset.waterfall.* (not all options)
The default chart options are:
options: {
plugins: {
waterFallPlugin: {
stepLines: {
enabled: true,
startColorStop: 0,
endColorStop: 0.6,
startColor: 'rgba(0, 0, 0, 0.55)',
endColor: 'rgba(0, 0, 0, 0)',
diagonalStepLines: true,
},
},
},
}
Dataset options:
dummyStack
: (boolean) If true then hides the tooltip, legend and sets the color to transparent.
Global/Chart options:
stepLines.enabled
: (boolean) If true then it shows the step-lines going from one bar to another.
Global/Chart/Dataset options:
stepLines.startColorStop
: (number) Used as the offset value in the first addColorStop
method call.
stepLines.startColor
: (string) Used as the color value in the first addColorStop
method call.
stepLines.endColorStop
: (number) Used as the offset value in the second addColorStop
method call.
stepLines.endColor
: (string) Used as the color value in the second addColorStop
method call.
For lines going from bar to bar that you need maximum customization over, see chartjs-plugin-custom-lines.
data
currently are not supported by this plugin.filter
method.
If you are providing your own filter method, using a custom tooltip or legend of your own then you will have to manually hide them because it will overwrite this plugins.E.g. This is how this plugin hides them, so you could do it this way:
filter: function(legendItem, chartData) {
var currentDataset = chartData.datasets[legendItem.datasetIndex];
return !currentDataset.dummyStack;
}
