around this issue I have a sap.m.table which has content in it, i want to add a column in the same table with sr.no and it should increment and decrement automatically when data is added and deleted respectively.The number should be added dynamically as per the data in the table. can anyone suggest me good solution for this problem. , Get your table's sPath from oContext...
For Example:
code :
oTable.bindAggregation("items", {
            path: "/",      //json is an array of rows
            factory: function(sId, oContext) { //this function is applied to each row

                var sPathindex = oContext.getPath();
                var index = parseInt(sPathindex.substring(1))+1;

                var serialNo = new sap.m.Text({text: index });
            }
           return colListItem = new sap.m.ColumnListItem({
                    cells:[serialNo ]
           });
  }

should help you out You can use GROUP_CONCAT and SUBSTRING_INDEX to pick one photo, if you want all the photos you can just use GROUP_CONCAT(photos.name) AS photo and you can get all the photos name by comma seperated list ,i have used ->group_by('vehicle.idvehicle'); so for one vehicle group all the photos will be merged by comma but as in your question you stated you need the one photo so i used the SUBSTRING_INDEX you can also get the latest photo by using the ORDER by in GROUP_CONCAT if photo id is auto incremented like SUBSTRING_INDEX(GROUP_CONCAT(photos.name ORDER BY photo.id DESC),',',1) AS photo
code :
$this->db
        ->select("vehicle.idvehicle, vehicle.mark,
         vehicle.model, vehicle.type, vehicle.author_id, users.nick, 
         SUBSTRING_INDEX(GROUP_CONCAT(photos.name),',',1) AS photo,",FALSE)
        ->from('xxxxxsld_auto.vehicle')
        ->join('users', 'vehicle.author_id = users.userid')
        ->join('photos', 'vehicle.idvehicle = photos.vehicle_id')
        ->group_by('vehicle.idvehicle'); 
        ->get()
        ->result_array();

this one helps. You can use FilterList to combine four SingleColumnValueFilter instances.

To fix the issue you can do One approach would be to convert the plt.total table into a long, "tidy" format, so that you can map to the matrix number instead of manually adding separate series.
Here we change the shape of the data to be long, with a new "matrix" field to denote which series the observation belongs to.
code :
plt.total.tidy <-
  plt.total %>%
  tidyr::gather(matrix, value, -R)
library(ggplot2)
p <- ggplot(plt.total.tidy, aes(R, value, color = matrix, lty = matrix)) +
  geom_line(size = 1.1) +
  theme(legend.position = c(0.1,0.1)) #+   
  # Could add below lines if you want to manually pick colors and linetypes
  # scale_color_manual(....) +
  # scale_linetype_manual(....) +

ggplotly(p) %>%
  layout(title = "", legend = list(x=0, y=0, font = list(family = "Times", size = 14, color = "#000")))
