I have a database with entries that are a as follows:
Each line has a field "productName", a field "date" and a field "price".
How can I draw a line graph which will give me in X axis the date and in Y axis the price and a line for every product.
In general how can we just choose what we want for our Y axis? what if I don't want to do any special metrics like "mean", "min", "max" and just want to plot the value of a field.
