![]() The first method XYChart.xAxis retrieves the Axis object that represents the x-axis. The above code sets the labels on the x-axis. In the above line of code, the argument is an array of numbers representing the values of the data points. This allows "combination charts" to be created easily by combining different layers on the same chart (eg., a chart containing a line layer on top of a bar layer). In ChartDirector, any chart type that has x-axis and y-axis is represented as a layer in the XYChart. The above code adds a bar layer to the XYChart. The origin (0, 0) is at the top-left corner.įor more complex charts which may contain titles, legend box and other things, we can use this method (and other methods) to design the exact layout of the entire chart. The y pixel coordinate is increasing from top to bottom. The x pixel coordinate is increasing from left to right. Note that ChartDirector uses a pixel coordinate system that is customary for computer screen. Since the entire chart is 250 x 250 in size, there will be 20 to 30 pixels margin for the text labels. In the above code, the top-left corner is set to (30, 30), and both the width and height is set to 200 pixels. We will leave some margin to allow for the text labels on the axis. The rectangle is specified by using the (x, y) coordinates of its top-left corner, together with its width and height.įor this simple bar chart, we will use the majority of the chart area to draw the bar chart. This is by specifying the rectangle that contains the bar chart. ![]() The second step in creating a bar chart is to specify where should we draw the bar chart. In ChartDirector, XYChart represents any chart that has x-axis and y-axis, such as the bar chart we are drawing. In this example, an XYChart object of size 250 x 250 pixels is created. The first step in creating any chart in ChartDirector is to create the appropriate chart object. This line imports the ChartDirector for Perl module. This ensures the Perl interpreter can find the ChartDirector for Perl module. ![]() *)/ Īdds "./lib" relative to the script directory to the Perl module search path. # Add a bar chart layer using the given data # Set the plotarea at (30, 20) and of size 200 x 200 pixels # Create a XYChart object of size 250 x 250 pixels ' + storeItem.# The ChartDirector for Perl module is assumed to be in "./lib" ' + storeItem.get('PROJECTED_USAGE_MONTH')) "> Pls let me know how I can get the X axis and Y axis values in code behind after reloading store ?Īctually, I am usng store load direct event.so I am able to get the chart data as json.but still wondering if there is any other way that avods lot of postbacks to server (that makes app really slow.) ? screenshot attached.how can i resolve this ?ĥ) Initially, I am binding empty data to chart store.but in an application event ( slider movement.) I have a direct method where i reload chart store based on this slider value. If not, how can i set minimum and maximum values dynamically in c# ? also let me know how i can do that in Javascript ? Also, if i set those values again ,ĭo i need to recreate / redraw the chart ? also let me know what else I should do once i set min and max values dynamically ?įyi, I am using ajax proxy to bind data to axes in the chart.so, once it is bound to the chart store, how can i take the minimum and maximum values ?Ĥ) I am using a vertical marker plugin for the chart.īut the vertical marker is not appearing on screen. , does it take the minimum value and maximum value of the y axis data that is bound from the Database ? So far, i have not seen any chart in examples with any negative values below X axis.Ģ) In another chart Application, I have X axis as Months and Y axis as some numbers that I retrieve from Database.the values in Y axis also have nulls in between the numbers like e.g, 1,3,null,null,6,8,null etc.Ĭurrently, the chart is behaving in such a way that nulls are considered as 0s in line series.hence the line series connects like this-īut, I want to connect only non-null numbers in the series.Let me know how i can accomplish that.ģ) In a chart, if i dont declare minimum and maximum values for the Y-axis ( any axis for that matter.) I have following questions regarding Line Chart:ġ) I want to create a line chart where the y-axis has both positive and negative values and I would like to display positive values above x-axis and negative values below x-axis ( X axis is on 0 ).
