Version 1

Hello,

Am sending the json data through the Post method via rest API URL and it is displaying on grid by using getDataTabeEntries service. now i want to create a chart by using two columns of data from the grid on the mashup. but am unable to create anytype of chart by using that data.

i want to show the values  chart of sensor value of a temperature and timestamp .

can anybody please help me out?

Please try to elaborate more.

Are you trying to use time series chart?

Make sure you are binding the data to the correct place in the chart - data source.

Please add screenshots, it can help.

Hello Assaf Elgov,

Thanks a lot for reply

I have attached the screen shots,

1 screen shot : The data is displayed on the grid, from that grid i want show the timestamp and sensor_2 value on the graph.

2. screenshot  : I have bind the data and you can able to see the connection also from the getDatatableEntries service. and in the property configuration, i can able to see only the time stamp field in x- axis but no other fields in the the data fields of y-axis

3 screen shot : i get empty graph with no single value.

Please specify in the service data shape for the infotable, then try to drag again, you should have options in the list

My service returns the output nothing.

i have defined the output to my service is "nothing".

I tried for the infotable also but its not working.

You need the output type to be infotable and also to set the data shape according to the data you are returning.

this is my service code, when i send the data through rest API, my data will directly display on the grid on mashup. as you said i have put output to infotable and added data shape also.

var values = Things["Gettankdt"].CreateValues();

values.device_key = jsonData.device_key; //STRING

values.app_version = jsonData.app_version; //STRING

values.sensor_2 = jsonData.nodes[0].sensor_2; //STRING

values.sensor_3 = jsonData.nodes[1].sensor_2;

values.sensor_4 = jsonData.nodes[2].sensor_2;

values.sensor_5 = jsonData.nodes[3].sensor_2;

values.sensor_6 = jsonData.nodes[4].sensor_2;

values.client = jsonData.client; //STRING

values.node_no = jsonData.nodes[0].node_no;//STRING [Primary Key]

values.node_no1 = jsonData.nodes[1].node_no;

values.node_no2 = jsonData.nodes[2].node_no;

values.node_no3 = jsonData.nodes[3].node_no;

values.node_no4 = jsonData.nodes[4].node_no;

values.device_no = jsonData.device_no; //STRING

values.device_type = jsonData.device_type; //STRING

values.timestamp = jsonData.timestamp; //NUMBER

values.timestamp = values.timestamp *1000;

me.timestamp = values.timestamp;

me.sensor_2 = values.sensor_2;

me.sensor_3 = values.sensor_3

me.sensor_4 = values.sensor_4

me.sensor_5 = values.sensor_5

me.sensor_6 = values.sensor_6

var params = {

values : values,

};

var id = Things["Gettankdt"].AddOrUpdateDataTableEntry(params);

var params = {

infoTableName : "InfoTable",

dataShapeName : "Gettankdatashape"

};

// CreateInfoTableFromDataShape(infoTableName:STRING("InfoTable"), dataShapeName:STRING):INFOTABLE(Gettankdatashape)

var result = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape(params);

Can you take screen shot of the service output ?
