#ANGULAR 4 - TREND GRAPH

version:1.0.6: It exploits the feature of change detections of Angular 4, so that the graphs are redrawn.

Light weight Angular 4 Trend graph, this aims at making the graphs with less browser rendering and painting.

Note: This graph is intended to show only the trend, not the values.

##Usage

'import TrendGraphModule' in the app.module.ts file. Use the following in the page: <trend-graph [data]="<graph_data>" [baseline]="<graph_Base_Value>" ></trend-graph>

###DATA The data is to be array of datasets in the following format:

[
    {
        data: Array<number>,
        borderColor: string,
        borderWidth: number
    }     
]

borderColor defines the line color and the borderWidth specifies the width of the line. As mentioned, data is an array, we can have multiple line graphs in the same graph.

Note: As of now the graph is not binded with the change events in data.

###BASELINE If baseline is defined then, the graph makes a horizontal line and makes the strokes below the line of desired color. the baseline is to be an object in the below format:

{
    yValue: number,
    borderColor: string,
    belowBaseLineColor: string,
    borderWidth: number;
}

-yValue determines the thresold value for the whole graph. -borderColor determines the line's color. -belowBaseLineColor defines the color of the strokes below the baseline.

Note: Baseline is optional. If no change in color below the baseline is required then specify the belowBaseLineColor same as of the graph's color.

The default value of belowBaseLineColor is red.
