Create horizontal lines with a label. This could be used to show notable values in the chart data (e.g. min, max, average). JSFiddle Demo
var horizonalLinePlugin = {
afterDraw: function(chartInstance) {

Denormalization and a flat database structure is neccessary to efficiently download separate calls. With the following structure, it is also possible to maintain two-way relationships. The disadvantage of this approach is, that you always need to update the data in multiple places.
For an example, ...
[TestCase(0, 0, 0)]
[TestCase(34, 25, 59)]
[TestCase(-1250, 10000, 8750)]
public void AddNumbersTest(int a, int b, int expected)
{
// Act
int result = a + b;
// Assert
Assert.That(result, Is.EqualTo(expected));
