Microsoft Charting Controls: Adding Charts Dynamically

So this is kind of repost as I had already posted this at StackOverflow but I thought it might have some merit here. Whatever. Charts are hot right now so I’m going to push the damned bandwagon. You don’t like it? Well then go do something to yourself that you would consider rude for me to suggest it. Anyways, this might have been overkill but hey, that’s me.

protected void Page_Load(object sender, EventArgs e)
Bench benchList;
FoodIntake foodIntakeList;
Panel panelChartHolder;

panelChartHolder = new Panel();

benchList = Bench.GetAll();
AddNewCharts(benchList, panelChartHolder, GetBenchXValue, GetBenchYValue);

foodIntakeList = FoodIntake.GetAll();
AddNewCharts(foodIntakeList, panelChartHolder, GetFoodIntakeXValue, GetFoodIntakeYValue);

Ok so this first part is simple. Create a panel to hold the charts you are adding, get the lists you want represented by the charts and call the method to create the charts.

  private void AddNewCharts(T[] listToAdd, Panel panelToAddTo,
     Func<T, DateTime> xMethod, Func<T, Int32>)

    ChartArea mainArea;
    Chart mainChart;
    Series mainSeries;

    mainChart = new Chart();
    mainSeries = new Series("MainSeries");

    for (Int32 loopCounter = 0; loopCounter < listToAdd.Length; loopCounter++)

    mainArea = new ChartArea("MainArea");


As you can see, I just created a new chart, added a series to it, and added a ChartArea to it. Next part is pretty much just looping through the collection and adding each item in it to the list itself. It uses the passed in delegate methods (Func) to get the X and Y values.

Last part holds the four methods responsible for getting the X and Y values from the two lists. Basically I did this to allow the chart creating method to be a generic as possible. Might be overkill.

  private DateTime GetBenchXValue(Bench currentBench)
    return currentBench.DateLifted;

  private Int32 GetBenchYValue(Bench currentBench)
    return currentBench.BenchAmount;

  private DateTime GetFoodIntakeXValue(FoodIntake currentIntake)
    return currentIntake.DateEaten;

  private Int32 GetFoodIntakeYValue(FoodIntake currentIntake)
    return currentIntake.Calories;

And so when you run this, you will get two graphs side by side. Mind you, they will be very plain as there are million different properties that can be set to improve the look. I guess the main point of this was to show that it’s pretty easy to create graphs dynamically using any kind of object list. You know what? Screw you. This is my blog and I’ll post whatever I want to. If you don’t like that then you can just come back at a later time and read something else I post. Yeah so there.
